The amino acids and polypeptide chains are important because of their role in the body for the synthesis of important molecules like proteins, neurotransmitters, enzymes, and hormones.

Amino acids are nitrogen-containing compound that helps to build protein. Hence, they are referred to as building units of proteins. These amino acids are not only required to synthesize protein but also required to synthesize other important nitrogen-containing compounds like peptide hormones, enzymes, neurotransmitters, and creatine.

A polypeptide is nothing but a chain made of amino acids. Two or more polypeptide chains help to form protein. This protein is used for the regular functioning of cells. It is also used to build up the structural components of the cell. They as enzymes help to speed up the biochemical reactions that occur in the body.

Answer:

Photosynthesis and cellular respiration are two processes that are essential to the survival of most living organisms. Both of these processes are involved in the conversion of energy and matter into forms that can be used by cells.

Photosynthesis is the process by which plants, algae, and some bacteria use energy from sunlight to convert carbon dioxide and water into glucose, a type of sugar. This glucose is then used by the cells as a source of energy. In the process of photosynthesis, oxygen is produced as a byproduct.

On the other hand, cellular respiration is the process by which cells convert the glucose produced by photosynthesis into energy. This energy is used by the cells to perform various functions, such as growth and reproduction. In the process of cellular respiration, oxygen is consumed and carbon dioxide is produced as a byproduct.

In summary, the reactants of photosynthesis are carbon dioxide and water, while the products are glucose and oxygen. The reactants of cellular respiration are glucose and oxygen, while the products are carbon dioxide and water.

Overall, energy and matter flow into photosynthesis in the form of sunlight and carbon dioxide, and flow out in the form of glucose and oxygen. In cellular respiration, energy and matter flow into the process in the form of glucose, and flow out in the form of carbon dioxide and water.

Explanation:

When exposed to light, photosynthesis uses organic substances such as carbon dioxide and water to produce glucose. This occurs in the green leaves of developing plants. As a byproduct of photosynthesis, glucose, oxygen, and water are produced.

Sugar is the first product of photosynthesis, and all plants convert it to starch. The breakdown of water into oxygen, which is then released, and hydrogen is the initial stage of photosynthesis. The use of direct light is required for this procedure.

Light energy is utilized in photosynthesis to transform carbon dioxide and water into glucose and oxygen. One glucose molecule and six oxygen molecules are created for every six carbon dioxide and water molecules.

The sum of the two intervening distances is larger than the distance between the outside genes DBT and ASPM (less than 33 map units). Why? because not all of the recombination events (double crossovers) are taken into account by the calculated distance between DBT and ASPM.

Thus, the map distance would have been greater if there were more double recombinants. Again, the map distance would decrease if the number of parents was higher. The map distance is lower here than anticipated. This indicates that the number of parents is higher than it ought to be.
