Glucogenic amino acids are used to make glucose for the brain. Others are oxidized in mitochondria via the citric acid cycle.
Glucogenic amino acids include glycine, serine, aspartic acid, glutamic acid, glutamine, valine, methionine, histidine, and arginine. Pyruvate, -ketoglutarate, succinyl CoA, fumarate, or oxaloacetate are the products of gluconogenic amino acid.Pyruvate and other intermediates of the citric acid cycle, which serve as precursors for gluconeogenesis, are produced during the metabolism of gluconogenic amino acids. Acetyl-CoA, which results from the conversion of ketogenic amino acids, produces ketone bodies. As the expression of BCAA aminotransferase (BCAT2), an enzyme that catabolizes the first step of BCAA degradation, is high in the skeletal muscle and low in, it is believed that the branched-chain amino acids (BCAAs; valine, leucine, and isoleucine) are metabolized and used as energy sources in the skeletal muscle [13].

how could dna extracted in these procedures be amplified for further analysis in a biomolecular laboratory. explain the polymerase chain reaction in your answer.
The copying process, known as polymerase chain reaction (PCR), uses an enzyme (polymerase) to replicate DNA regions in a test tube. By repeating the copying process, a small number of DNA molecules can be reliably increased up to billions within several hours.
When Dr. Kary Mullis found that DNA could be replicated in a lab much like it is in the natural world, DNA testing advanced substantially.
An enzyme (polymerase) is used in the polymerase chain reaction (PCR), a copying procedure, to replicate DNA sections in a test tube. A modest amount of DNA molecules can be reliably multiplied by billions in a matter of hours by repeating the copying process. A biological sample the size of a quarter is needed for RFLP analysis, while millions of copies of the DNA found in a few skin cells can be produced using PCR. The laboratory may be able to evaluate DNA evidence that has been severely damaged because PCR analysis only needs a tiny amount of DNA. While identifying, gathering, and preserving DNA evidence, more consideration must be given to contamination issues because the sensitive PCR technology replicates all DNA present in an evidence sample. Heat is applied at the beginning of the procedure to separate the DNA strands from the initial double-stranded DNA molecule, creating templates for each stand.
The complementary strand is subsequently created by the Taq DNA polymerase using nucleotides after primers have been added to the template strand. Since Taq polymerase can endure high temperatures, it is specially used. An extension is a procedure by which additional nucleotides are added, whereas annealing is the procedure by which primers are joined to the DNA strands.

at short focusing distances, ciliary muscles contract. what effect do these contractions have on the suspensory ligaments?
At short focusing distances, ciliary muscles contract causing the suspensory ligaments to tighten.
The ciliary muscle is an integral muscle of the eye that is constructed as a ring of smooth muscle in the middle layer of the eye, the uvea (vascular layer). It regulates the passage of aqueous humor into Schlemm's canal and governs accommodation for observing objects at different distances.
A suspensory ligament is a ligament that provides support to a body part, particularly an organ. The suspensory ligament protects the fetlock from hyperextension (i.e., falling too low) during exercise. The ligament begins in both the fore and hindlimbs at its connection to the back of the upper cannon bone.
When the ciliary muscle relaxes, its diameter increases; when the suspensory ligaments tighten, the lens becomes thinner. This occurs when concentrating on a celestial object. When the ciliary muscle contracts, the lens becomes much more circular and has more focusing power because the pressure on the zonular fibers is reduced. When the ciliary muscles relax, these fibers contract, pulling the lens out and creating a flatter shape with less focusing power

what is the net gain of atp or atp equivalent molecules from a c12-saturated acyl-coa under aerobic condition?
The ATP equivalent molecules from a c12-saturated acyl-coa under aerobic condition are 12 molecules.
This generates a complete of eight acetyl-CoA molecules, 7 NADH molecules and seven FADH2 molecules. Since a unmarried acetyl-CoA molecule fed into the citric acid cycle generates three NADH molecules, 1 FADH2 and 1 GTP, we see that a complete of 24 NADH, eight FADH2 and 8 GTP are produced while all eight acetyl-CoA cross into the citric acid cycle. Each acetyl CoA enters into citric acid cycle and yields 3 NADH2 (nine ATP), 1 FADH2 (2 ATP) and 1 GTP (1 ATP).
Therefore, altogether 12 ATP molecules could be made out of every mole of acetyl-CoA. The fatty acid CH₃CH₂CH=CHCH₂CH=CH(CH₂)₄COOH has twelve carbon. Hence the range of acetyl-CoA molecules produced could be 6 after numerous rounds of beta-oxidation.

if you inherit one dominant allele for dimples d and one recessive allele for no dimples what will be your genotype?
If you inherit one dominant allele for dimples d and one recessive allele for no dimples D , genotype will be Dd.
What is an allele?
The term "allele" was created to refer to a particular gene copy. Each copy (allele) of a gene, the DNA sequence that governs our features, is often found in two copies in eukaryotic genomes. A gene locus is a defined location on a chromosome that each allele resides in. The two alleles of the gene are shared by two homologous chromosomes, one received from each parent. Both dominant and recessive alleles are possible. Recessive allele effects are masked by the dominant allele (definition: the allele that is expressed) (definition: the allele that is not expressed).
Given, the presence of dimples is the dominant trait with genotype d. The recessive trait is absence of dimples with genotype D. Hence, the person who inherits both these alleles will be heterozygote will genotype dD and he will have dimples since it is the dominant trait and recessive trait will appear only is genotype is DD.If you inherit one dominant allele for dimples d and one recessive allele for no dimples D , genotype will be Dd.

Explanation:
How does crossing over lead to genetic variation ?
Genetic data is transferred between homologous chromosomes during crossing over. Through this exchange, novel gene combinations are formed, increasing the genetic diversity of the progeny.
Homologous chromosomes (one from each parent) pair along their lengths during meiosis. Chiasma points are where the chromosomes cross. The chromosomes split and reassemble at each chiasma, swapping some of their genes. Genetic variety is produced by this recombination. The exchange of genetic material between non-sister chromatids of homologous chromosomes, or crossing-over, takes place during prophase I. Remember that homologous chromosomes align in pairs, gene for gene down their whole length, generating a configuration with four chromatids known as a tetrad during prophase I.
A new mix of genetic data for the cell for a particular trait results from crossing over. By crossing over, organisms are prevented from being genetically identical from generation to generation. Variations in the genetic material that is passed down through the generations are made possible via genetic recombination. To boost genetic variety, chromosomes that are similar to one another cross across. A piece of one chromosome is swapped for another during crossing over. A hybrid chromosome with a distinctive genetic material pattern is the end outcome.

What Is the Carbon Cycle? Photosynthesis, Decomposition, Respiration and Combustion
In the carbon cycle, carbon dioxide is removed from the atmosphere by plants through photosynthesis and added to the atmosphere by animals and plants during cellular respiration. Burning fossil fuels increases the amount of carbon dioxide released into the atmosphere, which causes global warming. Option (a) is correct.
Thus, carbon can be found in a variety of substances, including coal and the hydrocarbons glucose and carbon dioxide. But today, we'll focus on the short-term carbon cycle, in which carbon simply circulates through the environment over a few days, weeks, or years. Photosynthesis: Process of photosynthesis, using photosynthesis, plants remove carbon dioxide from the atmosphere. Despite making up less than 1% of the atmosphere, carbon dioxide has a significant impact on life.
Nutrient Cycle: Decomposition of Plants can develop primarily by utilizing carbon dioxide, water, and sunlight. Animals then use food as fuel, exhaling CO2 and using oxygen. Alternately, they rot, deteriorate, and die again over the course of millions of years. In other words, through a process called respiration, plants use solar energy to break down the same carbon dioxide in the air. It converts that same carbon into plant material through photosynthesis, which then releases oxygen once more. Combustion, is the energy produced by burning fossil fuels is used by our automobiles. Carbon, like carbon dioxide, is a pollutant. Fossil fuels are extracted, and then they are burned to release energy. But carbon dioxide is returned to the atmosphere as a byproduct of burning.

What is the basilar membrane?
The scala media and the scala tympani, two liquid-filled tubes that go through the coil of the cochlea, are divided by the basilar membrane, a stiff structural component inside the cochlea of the inner ear. When sound waves enter the basilar membrane, they become traveling waves on the membrane, which cause the basilar membrane to rise and fall in response.
Due to the fact that low frequencies induce maximum membrane displacement at the apical end and high frequencies generate maximal membrane displacement close to the base of the cochlea (near the stapes). The wave must travel more to reach the peak if the sound constantly goes from base to apex.
Therefore the part of the basilar membrane responds to high frequency sounds is the base .
