light dependent reactions

and

light independent reactions

Term
What are the three stages of Interphase?
Definition
G1, S, G2
Term
How many membranes are there in a chloroplast?
Definition

2-inner and outer

plus a thykaloid membrane

Term
What are the inputs of the Calvin Cycle?
Definition
ATP, NADH+H+, CO2
Term
What are the outputs of the Calvin Cycle?
Definition
CH2O (sugar)
Term
Where does the Calvin Cycle take place?
Definition
stroma
Term
Where does the energy come from to drive the reactions of the Calvin Cycle?
Definition
light reactions
Term
What is the photosystem?
Definition
structure for capturing the light energy
Term
Where do the light reactions take place?
Definition
in thykaloid membrane
Term
What color does chlorophyll reflect?
Definition
green
Term
Why have so many different types of pigments as antenna pigments?
Definition
plants are exposed to white light (sunlight) so broadens the range of light the pigments can absorb
Term
What are the inputs of non-cyclic photophosphorylation?
Definition
light, H2O, ADP, NADP+
Term
What are the outputs of non-cyclic photophosphorylation?
Definition
O2, ATP, NADPH+H+
Term
What is the source of electrons for photosystem II?
Definition

water,

split to form 2 e-, 2 H+ions, 2 protons, 1/2O2

Term
What are the inputs of cyclic photophosophorylation?
Definition
light, ADP
Term
What is the output of cyclic photophosphorylation?
Definition
ATP
Term
What do the light reactions of photosynthesis supply the Calvin Cycle with?
Definition
ATP and NADPH
Term
What is the basic equation for photosynthesis?
Definition
6 CO2 + 6 H2O → C6H12O6 + 6 O2
Term

The light reactions of photosynthesis use _____ and produce _____.

 
Definition
water ... NADPH
Term
Which term describes ATP production resulting from the capture of light energy by chlorophyll?
Definition
photophosphorylation
Term
True or false? The chemiosmotic hypothesis states that the synthesis of ATP generates a proton gradient that leads to electron flow through an electron transport chain.
Definition
False
Term
According to the chemiosmotic hypothesis, what provides the energy that directly drives ATP synthesis?   
Definition
proton gradient
Term
True or false?  The region of ATP synthase that catalyzes the production of ATP from ADP and inorganic phosphate spans the chloroplast membrane.
Definition
False
Term

Chloroplast membrane vesicles are equilibrated in a simple solution of pH 5. The solution is then adjusted to pH 8. Which of the following conclusions can be drawn from these experimental conditions?

 
Definition
ATP will not be produced because there is no ADP and inorganic phosphate in the solution.
Term
