Question

Metabolic pathways that make available raw materials from which other molecules can be synthesized and that provide chemical energy required for many cell activities are known as ______.

1) anabolism
2) catabolism
3) manabolism
4) allosterism
5) anabolism and catabolism

Answer 1

Metabolic pathways that synthesize new molecules and provide chemical energy for cells are known as both anabolism and catabolism, which work together to maintain energy balance within the cell.

Step-by-step explanation:

The metabolic pathways that make available raw materials from which other molecules can be synthesized and provide the chemical energy required for many cell activities are known as both anabolism and catabolism. Anabolic pathways are those which require energy to synthesize larger molecules; whereas catabolic pathways are responsible for generating energy by breaking down larger molecules into simpler ones. Both pathways are crucial in maintaining a cell’s energy balance. An example of an anabolic process is glucose synthesis, and an example of a catabolic process is glucose breakdown.

Anabolism involves endergonic reactions which require the input of energy, while catabolism includes exergonic reactions which release energy. The energy collected from catabolic pathways is frequently used to drive anabolic pathways, effectively balancing the energy and material resources within the cell.
