Question

what is the advantage of highly folded membranes in a cell?
a. folding decreases the activation energy available on which chemical reactions occur.
b. folding decreases the surface area available on which chemical reactions occur.
c. folding increases the surface area available on which chemical reactions occur.
d. folding increases the activation energy available on which chemical reactions occur.

Explanation:

Folded membranes in cells, like those in mitochondria or endoplasmic reticulum, increase surface - area. More surface area provides more space for enzymes and other molecules involved in chemical reactions to bind and react. Activation energy is related to the energy barrier for reactions and is not affected by membrane folding.

Answer:

C. Folding increases the surface area available on which chemical reactions occur.
