b. It activates HCl.

c. It denatures protein structures.

a. tripeptides

Answer 1

QUESTION 37:-iN WHAT PROCESS THE MITOCHONDRIA OF CELLS INVOLVED .

Mitochondria are the powerhouses of the cell.where it takes up the nutients and break downs the compound molecules of the nutrients to simple molecules  and forms as the energy rich molecules in the form of ATP Adenosin Triphosphate.this all process happends in the matrix of the mitochondria this reaction known as kreb's cycle which produces the chemical called NADH which was used by the enzymes embbeded in the mitochondria and produces ATP.

hence the answer is conversion of pyruvate to ATP.

QUESTION 36:-

Anabolism means bringing up of smaller molecules and forms as larger molecules (compound molecules ) known as anabolism for this process energy is needed. where as catabolism is breaking down of compound molecules to simple molecules where it releases the energy which is take up by the body.

hence ans is option is'e' energy is required for anabolism

QUESTION 34:- what is fibrin.

Fibrin is defined as insoluble, non globular protien which was formed by the action of protease thrombin or fibrinogen which causes to the polymerize the fibrin which binds to the platelets and forms the platelet plug and forms as a mesh over the wound which impedes the flow of the blood.

hence the ans is option 'd' fibrin is a blood clotting protien

QUESTION 32:-WHAT HAPPENS WHEN PEPSIN ENTERS IN TO THE SMALL INTESTINE.

when pepsin enterns into the digestive tract of the small intestine it break downs the protiens into simple compound called peptides which can be easily absorbed by the small intestine and end enters into the blood stream.

hence the ans is option 'd' cleaves the protriens into smaller peptides and free from amino acids.
