Photosynthesis VS 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, and releasing oxygen as a byproduct.

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. It occurs in the mitochondria of cells.

Front

How do photosynthesis and cellular respiration differ in terms of gas exchange?

Back

Photosynthesis uses carbon dioxide and releases oxygen, while cellular respiration uses oxygen and releases carbon dioxide.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process that occurs in muscle cells when oxygen is scarce, converting glucose into lactic acid and producing a small amount of ATP.

Front

What is the significance of ATP in cellular respiration?

Back

ATP (adenosine triphosphate) is the main energy currency of the cell, providing energy for various cellular processes during cellular respiration.

Front

What happens during aerobic respiration?

Back

During aerobic respiration, glucose is completely broken down in the presence of oxygen to produce carbon dioxide, water, and a large amount of ATP.

Front

What happens during anaerobic respiration?

Back

During anaerobic respiration, glucose is partially broken down without oxygen, resulting in products like lactic acid or ethanol and a smaller amount of ATP.
