Question

Suppose you plant a seed and observe that a tree of large mass grows from it. The tree achieves a final mass that changes very little for years afterward. Which of the following is true about the tree?
A. Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing, but then all reactions stopped when the tree reached a stable mass.
B. Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing, and both continue now even though the tree reached a stable mass.
C.Only anabolic reactions
D.Only catabolic reactions

Answer 1

Suppose you plant a seed and observe that a tree of large mass grows from it. The tree achieves a final mass that changes very little for years afterward.

Answer: Of the options presented above the one that is true about the tree is answer choice B) Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing, and both continue now even though the tree reached a stable mass.

I hope it helps, Regards.

Answer 2

Answer is: B. Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing, and both continue now even though the tree reached a stable mass.

Food is broken in series of reactions called catabolism.

Catabolism (catabolic reactions) is the group of metabolic pathways that breaks down molecules of food (for example polysaccharides, lipids, proteins) into smaller units that are either oxidized to release energy or used in other anabolic reactions.

Anabolism (anabolic reactions) is the set of metabolic pathways that construct molecules from smaller units.
