Photosynthesis to prepare for exam 2

Glucose and O2

Products of overall net equation of Photosynthesis?

CO2, H2O and sunlight

Reactants of overall net equation of Photosynthesis?

Glucose

What product does the photosynthesizing organism use?

O2

What is the byproduct of photosynthesis?

Thylakoid membrane and space

Where do the light reactions of photosynthesis occur?

Stroma

Where does the Calvin Cycle of photosynthesis occur?

It captures light energy and coverts it into the stored energy of ATP and NADPH.

What does the light reaction stage of photosynthesis accomplish?

Clusters of proteins surrounded by light-harvesting pigments such as chlorophyll.

What are Photosystem 1 and Photosystem 2 composed of?

H2O

Photosynthesis is a redox reaction. What is Oxidized?

H2O reduced in thylakoid space, Electrons are charged by light reaction.

At Photosystem 2 what happens to H2O?

ATP and NADPH

The light reactions convert light energy into energy stored in:

O2, ATP and NADPH

What are the products of the light reaction stage?

H2O and light energy

What are the reactants used in the light reaction stage?

It takes CO2, ATP and NADPH and creates a glucose molecule.

What does the Calvin Cycle stage of photosynthesis accomplish?

Carbon fixation, reduction and regeneration.

What are the three major phases of the Calvin Cycle?

2 times

How many times must we do the calvin cycle to form a glucose molecule?

Thylakoid space and stroma

During the light reactions, a proton (H+) gradient is developed between what two areas of the chloroplast?

CO2

Photosynthesis is a redox reaction. What is REDUCED?
