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, 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.

Front

What are the two main products of photosynthesis that are used in cellular respiration?

Back

Glucose and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What is aerobic respiration?

Back

Aerobic respiration is a type of cellular respiration that requires oxygen to produce energy.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of cellular respiration that occurs without oxygen, producing less energy and resulting in byproducts like lactic acid or ethanol.

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.

Front

How do plants contribute to the oxygen supply in the ecosystem?

Back

Plants produce oxygen through photosynthesis, which is essential for the survival of aerobic organisms.
