Question

(iii) The substrate on which the enzyme Pepsin acts.
(iv) The cellular organelle which is energy​

Answer 1

Answer:

3)Pepsin acts on virtually all proteins except keratins, mucoproteins, and protamines. It catalyzes the hydrolysis of peptide bonds located in the interior of the protein chain. Due to this action, pepsin belongs to a family of enzymes known as endopeptidases.

4)The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).
