Question

Chemical reactions carried out by living systems depend on the ability of some

organisms to capture and use atoms from nonliving sources in the environment.
The specific subset of these reactions that break down nutrients in food can be
described as _____________.
(a) metabolic.
(b) catabolic.
(c) anabolic.
(d) biosynthetic.

Answer 1

(B) Catabolic.

Step-by-step explanation:

The metabolism refers to the chemical reactions which are used by the organisms to sustain their life therefore metabolism is considered a characteristic feature of the living organisms.

The metabolism involves either the formation of a molecule from the smaller subunits or monomer through a process known as anabolism and other involves the breakdown of the larger molecule into smaller subunits through catabolism.

In the given question, the breakdown of the food particle which is usually the complex biomolecules is broken down into simpler subunits through a catabolic reaction. The smaller subunits of molecules are easily absorbed ad then utilised by the body.

Thus, Option-B is the correct answer.
