Photosynthesis: Light Reactions (Acc: 2024-2025)

Front

What are the reactants of the Light Reactions in photosynthesis?

Back

Sunlight and Water.

Front

What are the products of the Light Reactions in photosynthesis?

Back

ATP, NADPH, and Oxygen.

Front

What is the role of ATP synthase in the Light Reactions?

Back

ATP synthase is a protein that embeds in the thylakoid membrane and allows H+ ions to flow through, facilitating ATP production.

Front

Which molecule acts as an electron carrier in the Light Reactions?

Back

NADPH.

Front

Where does ATP production occur in the chloroplast?

Back

In the thylakoid membrane.

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.

Front

What is the significance of sunlight in photosynthesis?

Back

Sunlight provides the energy required to drive the light reactions of photosynthesis.

Front

What is the function of water in the Light Reactions?

Back

Water is split to provide electrons, protons, and oxygen during the light reactions.

Front

What is the role of NADPH in photosynthesis?

Back

NADPH acts as an electron carrier, transporting electrons to the Calvin cycle for glucose synthesis.

Front

What is the thylakoid membrane?

Back

The thylakoid membrane is a membrane-bound compartment inside chloroplasts where the light reactions of photosynthesis take place.
