Question

Why is cellular respiration a necessary process for living things?

A) To produce oxygen
B) To release energy from food
C) To synthesize glucose
D) To regulate body temperature

Answer 1

Cellular respiration is necessary for living things as it releases energy from food in the form of ATP (adenosine triphosphate). This process involves breaking down glucose in the presence of oxygen and producing carbon dioxide, water, and energy.

Step-by-step explanation:

Cellular respiration is a necessary process for living things because it releases energy from food in the form of ATP (adenosine triphosphate). This process involves breaking down glucose in the presence of oxygen and producing carbon dioxide, water, and energy. Without cellular respiration, living organisms would not be able to obtain usable energy to power their cellular processes.
