Unit 6: Photosynthesis Flashcard

Front

What is the main purpose of photosynthesis?

Back

To convert light energy into chemical energy stored in glucose.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and the Calvin cycle (light-independent reactions).

Front

Where do light-dependent reactions occur in the chloroplast?

Back

In the thylakoid membranes.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, to initiate photosynthesis.

Front

What are the products of the light-dependent reactions?

Back

ATP, NADPH, and oxygen (O2).

Front

What is the Calvin cycle?

Back

A series of biochemical reactions that occur in the stroma of chloroplasts, using ATP and NADPH to convert CO2 into glucose.

Front

What is the chemical equation for photosynthesis?

Back

6 CO2 + 6 H2O -------> C6H12O6 + 6 O2.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is NADPH and its role in photosynthesis?

Back

NADPH is a high-energy electron carrier that provides the reducing power for the Calvin cycle.

Front

What is the stroma in a chloroplast?

Back

The fluid-filled space surrounding the thylakoids where the Calvin cycle takes place.
