BIO 9B - 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. It occurs in both aerobic (with oxygen) and anaerobic (without oxygen) conditions.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the chemical equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

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, which is essential for the process of photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, resulting in the production of energy and byproducts such as lactic acid or ethanol.

Front

What is aerobic respiration?

Back

Aerobic respiration is a type of respiration that requires oxygen to produce energy (ATP) from glucose, resulting in carbon dioxide and water as byproducts.

Front

What is the significance of the electron transport chain in cellular respiration?

Back

The electron transport chain is a series of protein complexes in the mitochondria that transfer electrons from NADH and FADH2 to oxygen, generating ATP through oxidative phosphorylation.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).
