Cell Energy

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

The equation for photosynthesis is: sunlight + carbon dioxide + water → glucose + oxygen.

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

The equation for cellular respiration is: glucose + oxygen → carbon dioxide + water + ATP.

Carbon dioxide is a key reactant in photosynthesis; it is used by plants to produce glucose.

If carbon dioxide is removed, no sugars will be produced.

Lactic acid fermentation is an anaerobic process that occurs in muscle cells when oxygen is scarce, converting glucose into lactic acid and energy.

Muscle cells undergo lactic acid fermentation during exercise.

An increase in oxygen levels will increase the rate of cellular respiration.

Yes, plants perform cellular respiration to convert glucose into energy.
