Everything You'll Have Covered

What essential source of chemical energy is produced through photosynthesis?

~ Glucose molecules are produced during photosynthesis and are the essential source of chemical energy for all living things.

What happens to glucose molecules during aerobic respiration?

~ During aerobic respiration, glucose molecules are broken down into smaller pieces, and energy is released.

What is produced during aerobic respiration?

~ Carbon dioxide and water are produced during aerobic respiration. Also, ATP molecules are produced from ADP molecules.

What is the purpose of aerobic respiration?

~ Plants and animals both obtain energy through aerobic respiration.

What is the relationship between photosynthesis and aerobic respiration?

~ The carbon dioxide and water produced during aerobic respiration are used as reactants in photosynthesis, and the glucose and oxygen produced during photosynthesis are used as reactants in aerobic respiration. The processes are thus opposites of each other.

What molecules are produced during photosynthesis?

~ Photosynthesis produces food (glucose), and oxygen molecules (O2).
