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.

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light reactions and the Calvin cycle (light-independent reactions).

Front

Where do the light reactions of photosynthesis occur?

Back

The light reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment that absorbs light energy, primarily from the sun, and initiates the process of photosynthesis.

What is the stroma in a chloroplast?

Back

The stroma is the fluid-filled interior space of the chloroplast where the Calvin cycle takes place.

Front

What is ATP and why is it important in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes, including the Calvin cycle in photosynthesis.

What is NADPH and its role 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.

What is the Calvin cycle?

Back

The Calvin cycle is the set of light-independent reactions in photosynthesis that convert carbon dioxide and other compounds into glucose.
