Photosynthesis Review

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 are the main products of the light-dependent reactions of photosynthesis?

Back

The main products of the light-dependent reactions are oxygen gas (O2), NADPH, and ATP.

Front

What is the role of water in photosynthesis?

Back

Water is split during the light-dependent reactions to provide protons and electrons, which are essential for the production of NADPH and ATP, and it is the source of oxygen gas released during photosynthesis.

Front

What is the function of stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow for the exchange of gases, specifically the intake of carbon dioxide and the release of oxygen.

What is RuBisCo and its role in photosynthesis?

Back

RuBisCo (Ribulose bisphosphate carboxylase/oxygenase) is an enzyme that catalyzes the first step of the Calvin Cycle, fixing carbon dioxide into an organic molecule.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is converted into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

How is oxygen gas produced during photosynthesis?

Back

Oxygen gas is produced when water is split during the light-dependent reactions, releasing oxygen as a byproduct.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is a crucial electron carrier that provides the reducing power needed for the synthesis of glucose in the Calvin Cycle.

Front

What is the role of ATP in photosynthesis?

Back

ATP serves as the energy currency in cells, providing the energy required for various biochemical reactions, including those in the Calvin Cycle.

Front

What are phototrophs?

Back

Phototrophs are organisms that obtain energy from light to produce organic compounds through photosynthesis.
