Photosynthesis - Overview

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 are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light reactions and the Calvin cycle.

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What are the products of the light reactions?

Back

The products of the light reactions are ATP, NADPH, and oxygen.

Front

What is G3P and its significance in photosynthesis?

Back

G3P (glyceraldehyde-3-phosphate) is a three-carbon sugar produced in the Calvin cycle, which can be used to form glucose and other carbohydrates.

Front

How many CO2 molecules are needed to produce one G3P?

Back

Three CO2 molecules are needed to produce one G3P.

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 fixed and converted into glucose.

Front

How many turns of the Calvin cycle are required to synthesize one G3P?

Back

Three turns of the Calvin cycle are required to synthesize one G3P.

Front

Where do the light reactions take place?

Back

The light reactions take place in the thylakoid membrane of the chloroplasts.
