The endocrine system is not a piece of the nervous system, but rather it is as yet basic to correspondence all through the body. This system is made out of organs, which emit concoction ambassadors known as hormones.
Answer:
B. Proteins
Explanation:
Salivary amylase is an enzyme that starts the breakdown of starch in the mouth. Gastric glands of the stomach secrete gastric juice, which contains HCl to kill bacteria and denatures proteins, intrinsic factors, and the enzyme pepsin. The chief cells of gastric glands secrete pepsinogen (an inactive form of pepsin).
Pepsin begins the digestion of proteins in the stomach. It breaks down certain peptide bonds between amino acids and thereby, breaks down protein chain into smaller peptide fragments. Pepsin requires a very acidic environment of the stomach (pH 2) and becomes inactive at a higher pH.
These ions bind to troponin, which forms a complex with tropomyosin. The process is called <span>Excitation-Contraction Coupling 3.</span>
It includes series of events, beginning with the production of an electrical impulse (action potential)<span> and ending with </span>contraction<span> of </span>muscles <span>in the </span>heart.
