Question

which of the following metabolic pathways is anabolic?
a) breakdown of actin in muscles
b) alcohol fermentation
c) cellular respiration
d) photosynthesis

Explanation:

Anabolic pathways build complex molecules from simpler ones. Photosynthesis builds glucose from carbon - dioxide and water using light energy. The breakdown of actin is a catabolic process. Alcohol fermentation and cellular respiration are catabolic as they break down organic molecules to release energy.

Answer:

D. photosynthesis
