Explain the role of catabolic and anabolic pathways in cellular metabolism.

A. Catabolic pathways break down molecules to release energy, while anabolic pathways build molecules using energy.
B. Catabolic pathways build molecules, while anabolic pathways break down molecules.
C. Catabolic and anabolic pathways are the same thing.
D. Catabolic pathways produce energy, while anabolic pathways consume energy.

Catabolic and anabolic pathways together regulate cellular metabolism. Catabolic pathways break down complex molecules into simpler ones, releasing energy in the process, while anabolic pathways build complex molecules from simpler ones, using energy. c) Catabolic and anabolic pathways are the same thing

Explanation:

Cellular metabolism involves a series of chemical reactions known as metabolic pathways, of which there are two main types: catabolic pathways and anabolic pathways.

Catabolic pathways are responsible for breaking down large, complex molecules into smaller ones. This process releases energy. An example of a catabolic pathway is the breakdown of sugar molecules.

On the other hand, anabolic pathways do the opposite - they build up complex molecules from simpler ones. This process requires energy. An example of an anabolic pathway is the synthesis of protein from amino acids.

Both types of pathways play a crucial role in maintaining the cell's energy balance. Consequently, in terms of energy and molecules, cells are constantly balancing catabolism with anabolism.
