HB: Photosynthesis Review 2024 - 2025

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 the role of chlorophyll in photosynthesis?

Back

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

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 the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.

Front

What is the primary function of the light-dependent reactions?

Back

The primary function of the light-dependent reactions is to convert light energy into chemical energy in the form of ATP and NADPH.

Front

What is carbon fixation?

Back

Carbon fixation is the process of converting inorganic carbon (carbon dioxide) into organic compounds (glucose) during the Calvin Cycle.

Front

What is the role of ATP in photosynthesis?

Back

ATP (adenosine triphosphate) provides the energy needed for various biochemical reactions during photosynthesis, particularly in the Calvin Cycle.

Front

What is NADPH and its role in photosynthesis?

Back

NADPH (nicotinamide adenine dinucleotide phosphate) is a carrier molecule that transfers high-energy electrons and is used in the Calvin Cycle to help convert carbon dioxide into glucose.

Front

What is the significance of the oxygen produced in photosynthesis?

Back

The oxygen produced in photosynthesis is a byproduct that is released into the atmosphere, which is essential for the survival of aerobic organisms.
