Answer:
(B) Catabolic pathways.
Explanation:
Catabolic pathway is the breaking down or degradation of complex molecules into simple molecules. Catabolic pathways are exergonic reactions because in the process of degradation, energy stored in these complex molecules is released. These reactions are spontaneous.
Examples of catabolic pathways are glycolysis, citric acid cycle, the breakdown of fat in adipose tissue to fatty acids, etc.
Answer: Sugar molecules contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.
