1. What two molecules are formed when a phosphate is removed from ATP?

There are three phosphate groups in ATP molecule (Adenosine Triphosphate), when removing one phosphate molecule, ADP molecule is formed (Adenosine Diphosphate).

2. What is the function of ATP? Describe the molecule.

The function of ATP is storing energy within a cell. ATP is adenosine triphosphate, C10H16N5O13P3, a high energy complex, giving the necessary power to push metabolistic reactions in the body. Its composed of adenosine, a ribose sugar, and three phosphates.

3. Describe how ADP is converted into ATP.

By adding one phosphate molecule to ADP, it becomes ATP.

4. Differentiate between oxidation and

It is reduced by hydrogen to make NADPH(2). FAD is not a hydrogen carrier in photosynthesis - its a hydrogen carrier in respiration.

Electrons pass along a chain of electron carriers during the light dependant stage of Photosynthesis. They lose energy in the process, which is used to photophosphorylate ADP into ATP. The electrons are thereafter combined with the hydrogens which combine with NADP forming the overall compound NADPH(2)

14. Where in the chloroplast does the ETC occur?

ETC takes place in the Cristae of the Mitochondria.

15. Where does the Calvin cycle occur?

The Calvin Cycle, also known as the dark reaction, occurs in the stroma.

16. What is the function of the Calvin cycle?

Synthesize simple sugars from carbon dioxide.

17. State the products of the Calvin cycle.

The immediate products of one turn of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules, 3 ADP, and 2 NADP+ (ADP and NADP+ are regenerated in the Light-dependent reactions).

18. Carbon fixation changes _CO2_ into _Organic Molecules_.

19. What is the source of the oxygen released during photosynthesis?

H2O - Oxygen is produced by photolysis of water.

20. Where does the carbon for making glucose come from?

The carbon in glucose, comes from carbon dioxide that enters through the plant through small holes on the bottom, called the stomata. After Calvin Cycle, it becomes glucose and other sugars.
