Photosynthesis Practice

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 is the overall chemical equation for photosynthesis?

Back

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of chloroplasts in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place, containing chlorophyll that captures light energy.

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis that convert light energy into chemical energy in the form of ATP and NADPH, releasing oxygen as a byproduct.

Front

What are light-independent reactions (Calvin Cycle)?

Back

Light-independent reactions, also known as the Calvin Cycle, use ATP and NADPH produced in light-dependent reactions to convert carbon dioxide into glucose.

Front

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes, including the light-independent reactions of photosynthesis.

Front

What is NADPH and its function in photosynthesis?

Back

NADPH (nicotinamide adenine dinucleotide phosphate) is a reducing agent that provides the high-energy electrons needed for the conversion of carbon dioxide into glucose during the Calvin Cycle.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere, and is essential for the respiration of most living organisms.

Front

What is the chemical formula for glucose?

Back

C₆H₁₂O₆
