Question

all cells need energy to perform various processes and to make molecules that are necessary to sustain their lives. from where do cells primarily get this energy?
a. water
b. mitosis
c. heat
d. food

Explanation:

Cells need energy to function. Water is a solvent and not a primary energy source. Mitosis is a cell - division process, not an energy source. Heat is a form of energy but not the primary source for cells. Food contains nutrients like carbohydrates, fats, and proteins. Through processes like cellular respiration, cells break down these nutrients in food to release energy in the form of ATP (adenosine triphosphate).

Answer:

D. food
