Q

what is the ATP/ADP cycle

A

Through a catabolic reaction, an enzyme breaks a glucose molecule which forms two pyruvic acids and releases energy. The released energy attaches phosphate to an ADP making it ATP.

Q

what is anaerobic respiration?

A

Through the process of glycolysis, a glucose molecule is snapped into two pyruvic acids releasing energy. If there is no oxygen then lactic acid molecules will form two ATP molecules.

Q

what is aerobic respiration

A

Pyruvic acid molecules move into the mitochondria where enzymes snap these acid molecules into 6 carbon dioxide and 6 water molecules which forms up to 36 ATP energy molecules.
