Photosynthesis and Cell Respiration CORE

Front

What is photosynthesis?

Back

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.

Front

What is the main purpose of photosynthesis?

Back

The main purpose of photosynthesis is to produce glucose, which serves as food for the plant, and to release oxygen as a byproduct.

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

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

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 cellular respiration?

Back

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

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is used as a reactant in cellular respiration to help break down glucose and release energy.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is the significance of the light-dependent reactions?

Back

The light-dependent reactions capture sunlight and convert it into chemical energy in the form of ATP and NADPH, which are used in the Calvin cycle.
