photosynthesis and cellular respiration

Front

What is photosynthesis?

Back

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

Front

What is cellular respiration?

Back

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

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O → C6H12O6 + 6O2

Front

What is the equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Front

What is the role of chloroplasts?

Back

Chloroplasts are organelles in plant cells where photosynthesis occurs, containing chlorophyll that captures light energy.

Front

What is the role of mitochondria?

Back

Mitochondria are organelles in cells where cellular respiration occurs, producing ATP from glucose.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process where glucose is converted into energy and lactic acid, occurring in muscle cells when oxygen is scarce.

Front

What is the significance of oxygen in aerobic respiration?

Back

Oxygen is essential in aerobic respiration as it acts as the final electron acceptor in the electron transport chain, allowing for maximum ATP production.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the importance of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in photosynthesis, used by plants to produce glucose and oxygen.
