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
Answer:
stem cells
Explanation:
Stem cells differ from other kinds of cells in the body. All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types.
23. Beause each parent cell have 23 and once u combine both it equals up to one cell which has 46 chromosomes.
Answer:
amoeba made up one of the only cells.
