AOnly the reactions that release energy
BOnly the reactions that consume energy
COnly the reactions taking place in mitochondria
DAll reactions inside cells, energy using and releasing
Answer & Solution
Correct answer: D. All reactions inside cells, energy using and releasing
1. All of the chemical reactions that take place inside cells make up the cell's metabolism.
2. That total includes both the reactions that use energy and the reactions that release energy.
3. Metabolism is therefore composed of building, called anabolism, and degradation, called catabolism.
4. Restricting it to one direction, or to one organelle, leaves out half or more of what the word covers.
