ANSWER: A living organism intakes food, it breaks down into mostly water and large organic molecules. These large organic molecules are Fat, Proteins, Glucose, Starch and Cellulose. These molecules are still not usable by the cells so the body breaks these large polymers into small monomers.
In cow's muscles, protein muscles are built by tapping 4 amino acid monomers. Fat muscles are built by tapping 3 fatty acid monomers and 1 glycerol molecule.
Cows use glucose molecules to mix with oxygen to release chemical energy in cellular respiration. Cows can make fat molecules and glucose molecules because fatty acids and glycerols are made up of same atoms, C, H and O.
Answer:
Glucose utilization would increase a lot.
Explanation:
Aerobic condition indicates the presence of large amount of oxygen in the body. Anaerobic condition means that the oxygen is limited or deficient in the body.
The muscle cells shows anaerobic condition during exercise and produces lactic acid. Since, the ATP demand is same in both the aerobic and anaerobic conditions. This increases the demand of glucose in the body. Glucose utilization is increased to provide proper energy to the individual.
Thus, the correct answer is option (a).
They form an ionic bond by exchanging one electron
Answer: The true statements about protein digestion and hydrolysis are;
1. Hydrochloric acid in gastric juices cause protein denaturation.
2. In small intestine trypsin attacks peptide bonds.
3.free amino acids are absorbed by the intestinal wall.
Explanation:
Protein digestion occurs in the duodenum and stomach and it is the breakdown of proteins to amino acids by action of Enzymes like trypsin, pepsin.
Protein is digested by the hydrolysis of carbon-nitrogen bond. Mechanical digestion of protein begins in the mouth and it continues in the small intestine and stomach.
Chemical digestion starts in the stomach where by hydrochloric acid in the gastric juice denatures the protein and convert pepsinogen to pepsin enzyme which convert the protein in food to peptides. Trypsin attacks the peptide bond that involves the carboxyl group which breaks it to polypeptide. Exopepdisases and dipeptidases breaks it down to amino acids. The amino acids released by protein digestion is then absorbed by the intestinal wall
