Q

what is the stroma?

A

the fluid matrix in the chloroplast

17
Q

What are the two reactions of photosynthesis?

A

Light dependent and light independent (Calvin cycle)

18
Q

What are the inputs and outputs of the light dependent reactions?

A

Inputs: light energy and H2O
Outputs: O2

19
Q

WHat are the inputs and outputs of the Calvin cycle?

A

Inputs: CO2
Outputs: C6H12O6

20
Q

Where does the light dependent reactions happen?

A

in the thylakoid membrane

21
Q

What are the 4 parts of the light dependent reactions?

A
  1. light energy is absorbed
  2. water is split
  3. NADPH and ATP are formed
  4. O2 is released
22
Q

Where does the calving cycle happen/

A

in the stroma

23
Q

What are factors of photosynthesis?

A

Temp, light intensity and CO2 concentration

24
Q

What is the graph for temperature vs rate of reaction?
