AIt stores surplus energy
BIt uses stored energy
CIt halts all metabolism
DIt doubles its heat output
Answer & Solution
Correct answer: B. It uses stored energy
1. Net energy change compares what catabolism releases with what anabolism spends.
2. When catabolic reactions release less energy than anabolic reactions use, the change is negative.
3. The body then draws on stored energy to make up the shortfall.
