Doesn't seem like anyone's here anymore but...
Here's everybody's second favorite topic to scare even more people off...

1. All of the following occur in cyclic photophosphorylation EXCEPT:
A. electrons move along an electron transport chain
B. electrons in chlorphyll become excited
C. ATP is produced
D. light energy is absorbed
E. NADPH is produced

2. How is C4 Photosynthesis different from C3 Photosynthesis
A. C4 plants require less water for photosynthesis than do C3 plants
B. C4 plants can photosynthesize better in lower levels of light than C3 plants
C. C4 plants are more efficient CO2 fixers than are C3 plants
D. In C4 plants, chlorophyll P680 is more efficient than it is in C3 plants
E. Because C4 plants have special alkaloids (toxic substances) C4 plants are able to resist pests better than are C3 plants

From my review book, didn't feel like searching for old tests, you all know me ;-P
though you're going to hate me for the topic...

1. Which of the following sequences correctly indicates the potential ATP yield of the indicated molecules from the greatest ATP yield to the least ATP yield
A. Pyruvate, ethanol, glucose, acetyl CoA
B. Glucose, pyruvate, acetyl CoA, NADH
C. Glucose, pyruvate, NADH, acetyl CoA
D. Glucose, FADH2, Acetyl CoA, pyruvate
E. Glucose, FADH2, NADH, pyruvate

2. Chemiosmotic theory describes how ATP is generated from ADP. All of the following statements conform to the principles of the thoery EXCEPT
A. H+ accumulate in the area between the membrane of the cristae and the outer membrane of the mitochondrion
B. A pH gradient is created across the cristae membranes
C. a voltage gradient is created across the cristae membranes
D. A proton gradient is created across the cristae membranes
E. Electrons flowing through the ATP synthase channel protein provide the energy to phosphorylate ADP to ATP

Yeah... so... questions...

1)Which is NOT associated with a signal transduction pathway?

2)The active site of an enzyme is similar to the _________ of a catalyst.
a.catalytic center
b.allosteric site
c.substrate bind site
d.activity center
e.reaction site

3)Which of the following is NOT a result of the hydrogen bonds in water?
c.high specific heat
d.density of ice
e.evaporative cooling

I'll post the answers in a comment cause that's easier.

Now, more importantly, does anyone else think mr. scott's obsession with the pointer is proof that he's actually just a really tall six-year-old?
