Title: Glucose may diffuse into a cell down a
1(No Transcript)
2Glucose may diffuse into a cell down a
- Chemical gradient
- Electrical gradient
- Electrochemical gradient
3Glucose may be pumped into a cell by
- An ATPase
- Facilitated diffusion
- A Na antiporter
- 1 and 3
4The electrical gradient across a cell membrane is
produced by
- K leak channels
- Na leak channels
- Na/K ATPases
5How many ATPs are produced maximally in an
aerobic cell converting glucose to 6 CO2?
6How many ATPs are produced maximally in an
aerobic cell converting 2 pyruvate to CO2?
7How many ATPs are produced maximally in an
aerobic cell converting 3-P-glyceraldehyde to
acetyl CoA?
8How does the cell make more OAA to fill up the
citric acid cycle?
- Carboxylation of pyruvate
- Oxidative decarboxylation of pyruvate
- Condensation to form citrate
- Oxidation of citrate
9What has the lowest pH?
- The thylakoid space of a chloroplast
- The stroma of a chloroplast
- The intermembranal space of a mitochondrion
- The matrix of a mitochondrion
10Which has the largest redox potential?
11Which of the following is not a proton pump?
- Complex I
- Complex II
- Complex III
- Complex IV
12Which of the following rotate in the operation of
the ATP synthase?
- C12
- a
- Stator
- (Alpha-beta)3
- All of the above
13What is the order of conformational changes in
the F1 particle?
14Inorganic phosphate (Pi) enters the matrix by H
ion cotransport. The transporter is a(n)
- Antiporter
- Symporter
- Uniporter
- ATPase
15Oligomycin plugs the FO and
- Eventually blocks electron transfer
- Stops ATP synthesis
- Destroys the proton gradient
- 1 and 2
- All of the above
The word destroy means to eliminate, demolish,
kill, take away, blow to smithereens, smash, and
make non-existant,
