Question

question 6 which of the following best summarizes cellular respiration? organisms change nitrogen into a form that can be used by cells. organisms break down food and oxygen molecules to form new compounds and release energy. organisms use carbon dioxide, water, and sunlight to make food. organisms use carrier proteins to transport molecules into the cell.

Explanation:

Cellular respiration is the process by which organisms break down food (glucose) and oxygen molecules to form new compounds (carbon - dioxide and water) and release energy. The first option is about molecule transport, the second is about photosynthesis, and the fourth is about nitrogen - fixation.

Answer:

Organisms break down food and oxygen molecules to form new compounds and release energy.
