Which of the following statements is be l1 u:xq fle8+qst dep , p+eic ibsue8 86jg3micted by the 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 synthesis of a more complex compound from simpeag8j6ozfn64 q80yc2vrwly z 5j,tc 6ler molecules and therefore is a depiction of an anabolic reaction.
Reaction X cannot be catabolic (Choice A) since a more complex molecule is produced. Catabolism results in simpler products comparv8z6 fwrc j 0aen6t oj4z2gqly,yc685 ed 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).
