Question

Food molecules like sugar are broken down to form carbon dioxide and water. During this process, bonds between food molecules are broken to release energy. What is the primary use of the released energy? A to perform cell functions. B to release heat and light C to break down simple molecules D to circulate nutrients in the body​

Answer 1

A) to perform cell functions

Step-by-step explanation:

The primary use of the energy released during the process of breaking down food molecules like sugar is A) to perform cell functions.

During cellular respiration, the energy from the broken bonds in food molecules like sugar is used to generate ATP (adenosine triphosphate), which is the primary energy currency of cells. This energy is used for a variety of essential cell functions, such as cell growth, repair, and reproduction, as well as for the active transport of molecules across cell membranes and for muscle contraction.

B) releasing heat and light is also an important byproduct of cellular respiration, but it is not the primary use of the energy released.

C) breaking down simple molecules is not the primary use of the energy released.

D) circulating nutrients in the body is not the primary use of the energy released, but the energy is used to transport molecules and nutrients throughout the body.
