Photosynthesis

Front

What is the primary function of photosynthesis?

Back

The primary function of photosynthesis is to 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 (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 produced during the light reactions of photosynthesis?

Back

The light reactions produce ATP, NADPH, and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily in the blue and red wavelengths, and is essential for the light reactions of photosynthesis.

Front

What is the significance of the stroma in photosynthesis?

Back

The stroma is the fluid-filled space in chloroplasts where the Calvin cycle (light-independent reactions) takes place.

Front

What are autotrophs and how do they relate to photosynthesis?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis; they contain chloroplasts to perform photosynthesis.

Front

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 using ATP and NADPH.

Front

What are the two products of the light reactions that are essential for the Calvin cycle?

Back

The two products of the light reactions that are needed for the Calvin cycle are NADPH and ATP.

Front

How does temperature affect the rate of photosynthesis?

Back

High temperatures can slow photosynthesis because they can denature enzymes involved in the process.
