Why are two phosphate groups added to glucose in stage one of
glycolysis?
A) To destabilize the intermediates in stage one, making the
stage two reactions more favorable.
B) To provide all of the phosphate for ATP synthesis during
stage two.
C) To increase the net ATP produced from one glucose
molecule.
D) To activate the enzymes in stage two.
For Glycolysis, TCA cycle and Electron Transport, be able to
name all the intermediates and what each step consumes or releases
(NADH, ATP etc) Know the differences between GLUT 1, 2, 3 and 4
The addition of phosphate groups to intermediate molecules in
glycolysis results in:
a.
Increased potential energy of that intermediate molecule
b.
Use of ATP
c.
Subsequent generation of ATP via substrate-level
phosphorylation
d.
Direct generation of ATP via oxidative phosphorylation
e.
A, B, and C are correct
Which of the following statements regarding electron excitation
in photosynthesis is correct?
a.
All forms of electromagnetic radiation are equally capable of
generating free radicals
b.
All wavelengths of light induce equal degrees...
In glycolysis, a glucose-phosphate is transformed into a
fructose-phosphate. Which of the following reasons provides the
best chemical rationale for this transformation? Choose the best
answer.
A.
It is not possible to break a molecule of glucose into two
pieces but it is possible to break a molecule of fructose into two
pieces.
B.
Glucose is not a high phosphotransfer potential molecule but
fructose is a high phosphotransfer potential molecule.
C.
There are no enzymes to add phosphate groups to...
Explain, using electron-pushing arguments, why glycolysis must
go through the Glucose 6-Phosphate to Fructose 6-Phosphate step
(i.e. a C1 aldehyde to a C2 ketone).
Focus on the subsequent aldolase-catalysed reaction and explain why
Glucose 1,6 bisphosphate would not be able to go through the
aldolase reaction.
is it a phosphate system, slow glycolysis, fast
glycolysis, beta oxidation, or transamination/deamination?
1. protein will be used as fuel is depleted of
fuel
2. can be enhancing by eating more red meat.
3. recovered in 60 min.
4. 1 atp per one substrate used
5. results in co2 and h20
6. complete depletion of carbs
7. predominant system for long distance endurance between 60 to
70%
8. clear lactate fast than it is produced
9.predominant system for long distance...
Human cells contain a protein that binds to the 5? triphosphate
groups of RNA. Explain why this protein would be part of the
defense against viral infection.
2. a. Why do cell extracts require
NAD+ to convert
glucose to pyruvate? What intermediates accumulate when
NAD+ is absent?
Explain. b.Why does the rate at which glucose is converted to
pyruvate decrease when citrate is added?
