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.
Answer:
The cytosol is best described as semifluid substance in which organelles are suspended.
Explanation:
Cells have different components. They can be divided in eukaryotic and prokaryotic. When it comes to the first type, they have a defined membrane for the nucleus. When it comes to the second ones, they have their nucleus in all the cytosol. <em>The cytosol is the space in the cell made of a semifluid subtance with different organelles suspended</em>.
Just to mention some of the organelles that can be there, we can find mitochondrion
, endoplasmic reticulum
, centriole
, among others.
The cell theory is the idea that the basic unit of life is cells.
