Test: Biochemistry

1.

Why are the enzymes in lysosomes better and more active at an acidic pH than at a neutral pH?

It prevents them from accidentally degrading the macromolecules in the cytosol

It allows for regulation of their uptake by mitochondria

Since lysosomes are primarily found in the stomach acid of mammals, their pH dependence allows for maximum efficiency for the digestion of foodstuffs

It prevents their diffusion out of the lysosomes

It maximizes the interaction with their substrates, which are always bases
