Photosynthesis miller & levine pt 1

What is ATP ? What purpose does it serve?

• Adenosine Triphosphate, a pigment that absorbs light

• Adenosine Triphosphate, the basic energy source for all cells

• Adenosine Diphosphate, a molecule that stores 90x more energy than required to add a phosphate group

• Adenosine Diphosphate, a molecule that transfers high-energy electrons and hydrogen to the Calvin Cycle

What is the role of chlorophyll in photosynthesis?

• It is a fluid portion known as the stroma.

• It is a high energy electron carrier.

• It is a chemical compound that absorbs light.

• It is an organelle where photosynthesis takes place.

What is the chemical reaction of photosynthesis as described in the document?

• 6CO2 + 6H2O (light) -> C6H12O6 + 6O2

• 6O2 + C6H12O6 -> 6CO2 + 6H2O (light)

• CO2 + H2O -> O2 + C6H12O6 (light)

• C6H12O6 + O2 -> CO2 + H2O (light)

What is the main function of the Calvin Cycle in photosynthesis?

• To produce high-energy sugars from carbon dioxide and water using light.

• To generate ATP and NADPH to be used in the light-dependent reactions.

• To remove CO2 from the atmosphere and produce a single 6-carbon sugar molecule.

• To absorb light energy and produce glucose and oxygen.
