Which of the following statements is ;m/ k6n8zybxy best depicted by the i ;at(5)kv urc figure below?
A. Reaction X is a representation of anabolic reactions.
B. Reaction X is a representation of catabolic reactions.
C. Reaction X is a representation of all metabolic reactions.
D. Reaction Y is a representation of anabolic reactions.
参考答案: A
本题详细解析:
Reaction X represents the synthess qfb;u+uv-u 5is of a more complex compound from simpler molecules and therefore is a depiction of an anabolic reactif-qbs5 uuu v+;on.
Reaction X cannot be catabolic (Choice A) since a more complex molecule is produced. Catabolism results in simpler products compared to the reactants. Reaction X cannot represent all metabolic reactions (Choice C) since metabolic reactions include both anabolic and catabolic reactions while reaction X represents only anabolic reactions. Reaction Y represents a catabolic reaction and not an anabolic reaction (Choice D).
