Question

which of the following best describes cellular respiration? a the transport of materials within cells b the conversion of light energy into chemical bond energy c the change of energy in food to a form usable by organisms d the removal of oxygen from an organisms cells

Explanation:

Cellular respiration is the process by which cells break down glucose (from food) and convert its stored energy into ATP (adenosine triphosphate), a form of energy that organisms can use. Option A is about material transport, not energy conversion. Option B describes photosynthesis (not cellular respiration). Option D is incorrect as cellular respiration uses oxygen (not removes it from cells in the way described).

Answer:

C. the change of energy in food to a form usable by organisms
