Photosynthesis

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 are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the Light Dependent Reactions and the Calvin Cycle (Light Independent Reactions).

Front

Where do the Light Dependent Reactions occur?

Back

The Light Dependent Reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in the chloroplasts that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is produced during the Light Dependent Reactions?

Back

During the Light Dependent Reactions, ATP, NADPH, and oxygen are produced.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is fixed into glucose using ATP and NADPH.

Front

What is the function of ATP Synthase in photosynthesis?

Back

ATP Synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate, using the energy from the flow of hydrogen ions across the thylakoid membrane.

Front

What is the significance of NADP+ in photosynthesis?

Back

NADP+ is an electron carrier that accepts electrons during the Light Dependent Reactions, becoming NADPH, which is used in the Calvin Cycle.

Front

What is the primary source of energy for photosynthesis?

Back

The primary source of energy for photosynthesis is sunlight.

Front

What role do roots play in photosynthesis?

Back

Roots absorb water and minerals from the soil, which are essential for photosynthesis.
