AIt breaks large molecules down and releases energy
BIt moves ions across membranes using stored gradients
CIt builds complex molecules and requires energy input
DIt converts kinetic energy directly into heat energy
Answer & Solution
Correct answer: C. It builds complex molecules and requires energy input
1. Anabolic pathways require an input of energy to synthesize complex molecules from simpler ones.
2. Synthesizing sugar from carbon dioxide is one example, and building large proteins from amino acids is another.
3. Catabolic pathways do the reverse, degrading complex molecules into simpler ones and releasing energy.
4. So the first option describes catabolism, which is the standard confusion between the two words.
