1
Q

Photosynthesis occurs in 2 stages. Name each stage and where they take place.

A

Light dependent happens on the Thylakoids membrane. Light independent happens in the stroma, outside of the thylakoid.

2
Q

The two reactants of photosynthesis are carbon dioxide and water. In which reaction is each used?

A

Water is used in Light Dependent.

CO2 is used in Light Independent.

3
Q

What is the purpose of the light dependent reaction?

A

To create two unstable high energy molecules, and release Oxygen into the atmosphere.

4
Q

What happens to the high energy electrons that are produced in photosystem 1?

A

They go on to aid in the creation of NADPH from NADP+

5
Q

What is the name of the enzyme in the thylakoid membrane that is used to produce ATP?

A

Phosphate

6
Q

Where does the Calvin cycle take place?

A

In the chloroplasts.

7
Q

Look in your book at the end of Chapter 8 section 3 and explain the 3 factors that affect the rate of photosynthesis.

A

Temperature, some enzymes that aid Photosynthesis do best at 0 - 30° C
Light intensity, the less light the slower the electrons are exited
Water, since water is necessary, a shortage can slow or stop Photosynthesis.

8
Q

What powers the rotation of the ATP synthase molecule?

A

H+ ions flowing from high to low concentration

9
Q

What splits off mid-cycle in the Calvin cycle to create sugar molecules?

A

2 3-Carbon molecules

10
Q

What is the overall purpose of the Calvin cycle?

A

To create high-energy sugars!!!!!! Yay!
