Photosynthesis - Light Reactions

Front

What does the Z-Scheme analogy diagram represent?

Back

The Z-Scheme analogy diagram represents the light reactions of photosynthesis.

Front

What are the stacks of disks in the chloroplast called?

Back

Grana.

Front

Where do the light reactions take place in the chloroplast?

Back

In the Thylakoid Membrane.

Front

Where do the electrons for the light reactions come from?

Back

Water.

Front

What are the disks in the chloroplast called?

Back

Thylakoids.

Front

What is the primary function of the light reactions in photosynthesis?

Back

To convert light energy into chemical energy in the form of ATP and NADPH.

Front

What is the role of chlorophyll in the light reactions?

Back

Chlorophyll absorbs light energy, which excites electrons and initiates the light reactions.

Front

What is produced as a byproduct of the light reactions?

Back

Oxygen.

Front

What is the significance of the thylakoid membrane in photosynthesis?

Back

The thylakoid membrane houses the proteins and pigments necessary for the light reactions.

Front

What is the difference between light reactions and dark reactions?

Back

Light reactions require light to produce ATP and NADPH, while dark reactions (Calvin cycle) use these products to synthesize glucose.
