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:
Longer hydrocarbon molecules have a stronger intermolecular force. More energy is needed to move them apart so they have higher boiling points . This makes them less volatile and therefore less flammable .
Euglena is a genus of single-celled eukaryotes, so I think the answer is A.
Answer:
The parts of the biodome that contain carbon are known as the biosphere.
Explanation:
•This is because a biodome is a form of a scientific model that is established to illustrate or simulate a certain environment, including the area which contains both living things and nonliving things while observing their interaction.
•Both plants and humans are in biospheres, and they both make use of carbon dioxide to function for photosynthesis and respiration.
Hence, The parts of the biodome that contain carbon are known as the biosphere.
Answer:
Because the blood has both the A and B antigen.
Explanation:
This means that if the blood produced an A antibody or a B antibody, the body would attack the antigens in its own blood.
