How could an error during transcription affect the protein that is produced apex.
The error during transcription affects the protein that is produced by (B) The protein would be made of the wrong nucleic acids.
The process of producing mRNA out of a DNA molecule takes place in the cellular nucleus and is known as transcription. The RNA polymerase enzyme is used to mediate the process. The messenger RNA, or mRNA, transmits genetic data or genetic codes, which are later used in the translation process to produce proteins.
Codons, which are aligned with genetic information, forecast the amino acids and, in turn, the protein that will be created. Therefore, a transcription error denotes a change in base pairs, which further denotes a change in codons, and then different amino acids, which would ultimately result in the production of an erroneous protein.

Answer: The protein could be made of a wrong nucleic acid
Explanation:
The protein produced is altered by the transcriptional mistake. The incorrect nucleic acids would be used to make the protein.
Transcription, which takes place in the cellular nucleus, is the process of converting a DNA molecule into mRNA. The process is mediated by the RNA polymerase enzyme. In order to generate proteins, the messenger RNA, or mRNA, transmits genetic information or genetic codes. Codons predict the amino acids and, consequently, the protein that will be produced since they are in line with genetic information. As a result, a transcription error indicates a change in base pairs, which further indicates a change in codons, followed by different amino acids, which would finally produce an incorrect product.

Put the enzymes of the first half of the citric acid cycle in order from left to right.
a. α-ketoglutarate dehydrogenase
b. citrate synthase
c. isocitrate dehydrogenase
d. aconitase
citrate synthase, aconitase, isocitrate dehydrogenase, α-ketoglutarate dehydrogenase is the correct order.
What are the steps of citric acid cycle?Step 1:
The two-carbon acetyl group (from acetyl CoA) is combined with a four-carbon oxaloacetate molecule in the first step to create a six-carbon citrate molecule. The sulfhydryl group (-SH) that CoA is linked to diffuses away and finally joins with another acetyl group. Due to its strong exergonic nature, this action cannot be undone. The availability of ATP and negative feedback both affect how quickly this reaction proceeds. The pace of this process reduces as ATP levels rise. The rate increases when ATP is scarce.
Step 2:
As citrate is transformed into its isomer, isocitrate, it loses one water molecule and gets another.
Step 3 and 4:
Isocitrate is oxidized in step three, resulting in the formation of the five-carbon molecule -ketoglutarate, a molecule of CO2, and two electrons that decrease NAD+ to NADH. ADP's beneficial effect and the negative feedback from ATP and NADH both influence this process. By releasing electrons that convert NAD+ to NADH and carboxyl groups that release CO2 molecules, steps three and four are both oxidation and decarboxylation processes. The results of steps three and four are -ketoglutarate and a succinyl group, respectively. To create succinyl CoA, CoA binds to the succinyl group. ATP, succinyl CoA, and NADH all function as feedback inhibitors, which control the enzyme that catalyses step four.
Step 5:
Coenzyme A is replaced with a phosphate group, and a high-energy link is created. When the succinyl group is changed into succinate, this energy is utilized in substrate-level phosphorylation to create either guanine triphosphate (GTP) or ATP. Depending on the kind of animal tissue they are present in, there are two isoenzyme versions of the enzyme for this step. One type is present in organs like the heart and skeletal muscle that require a lot of ATP. This kind generates ATP. The liver is one of the tissues that contains a lot of anabolic pathways and hence contains the second version of the enzyme. This kind generates GTP. Energy-wise, GTP is equal to ATP, but its application is more constrained. GTP is particularly important for protein synthesis.
Step 6:
Dehydration is the sixth step, which changes succinate into fumarate. Transferring two hydrogen atoms to FAD results in FADH2. Although these atoms' electrons have enough energy to reduce FAD, they lack the necessary energy to reduce NAD+. This carrier, as opposed to NADH, stays affixed to the enzyme and directly delivers the electrons to the electron transport chain. The enzyme that catalyses this step is situated inside the inner membrane of the mitochondrion, which enables this process.
Step 7:
In step seven, fumarate is mixed with water to create malate. Oxidizing malate is the final stage in the citric acid cycle that regenerates oxaloacetate. Another NADH molecule is created.

During times of relaxation, the ______ division of the autonomic nervous system utilizes discrete and localized innervation, stimulating only one or a few structures at the same time.
The parasympathetic nervous system is used in times of relaxation.
The parasympathetic nervous system is a network of nerves that help the body to relax after exposure to stress or danger. It also helps sustain life-supporting processes such as digestion when you are safe and relaxed. Informal descriptions of this system include the rhymes "rest and digest" or "feed and breed."
The parasympathetic nervous system is part of the autonomic nervous system. It is often called the "automatic" nervous system because it is responsible for many functions that you don't have to think about controlling. The parasympathetic portion of the autonomic nervous system balances the sympathetic nervous system.

When necessary, animals like us may break down the glucose polymer known as glycogen back into its monomer form.
Both fungi and animals use the glucose polymer known as glycogen to store energy. The primary glucose storage type in the body is shown by the polysaccharide structure of glucose. The cells of the liver and muscles create and store glycogen while being hydrated with the four parts of water. It functions as a long-term energy storage reserve. Glycogen in muscles is quickly transformed into glucose by muscle cells, whereas liver glycogen does the same for the entire body, including the central nervous system.
Glycogen is a long polymer chain of glucose molecules joined by an alpha-acetal bond.
This acetal bond is created when the alcoholic and carbonyl groups combine. If the carbonyl group is an aldehyde group i.e(-CHO) and also termed as hemiacetal if there is a ketonic group. The acetal group is what results from the bonding of two alkoxy groups to the same carbon atom.

The head of the humerus, which sits on the glenoid fossa of the scapula, forms the shoulder joint (or shoulder blade). In contrast, the hip joint is made up of the acetabulum of the ilium and the head of the femur (pelvic bones). But compared to the hip, the shoulder can dislocate significantly more quickly. The shoulder socket is rather small. This increases its mobility. It is held in position by ligaments, tendons, and muscles. Similar to how a golf ball interacts with a tee, the joint surfaces move together. The joint is fundamentally less stable than one with a real ball and deep socket, like the hip joint, because the socket is very shallow and smaller than the ball.
