Glycolysis
|
“Step 1 ½”
|
Kreb’s Cycle
|
Electron Transport Chain
|
- Where
in the cell does this process take place?
|
Cytoplasm only
|
Cytoplasm to mitochondrial membrane
and eventually into the matrix
|
in the Matrix
|
On the inner membrane & in
the intermembrane space
|
- How
much Net ATP is formed at this step?
|
2
|
0
|
2
|
34
|
- Is
the ATP formation called oxidative phosphorylation or
substrate level phosphorylation?
|
Substrate level
|
no ATP formed here
|
Substrate level
|
Oxidative
|
- How
much NADH and/or FADH2 is formed at this
step?
|
2 NADH
|
2 NADH
|
6 NADH
2 FADH2
|
none formed
(all are used here)
|
- Starting
reactant(s) and ending product(s) of each step.
|
Glucose
à
2
Pyruvates
|
2
Pyruvates ->
2
CO2 + 2 Acetyl CoA
|
2 Acetyl CoA ->
4 CO2
|
None left
(here the NADH and FADH2 are losing electrons)
|
- Carbon
rearrangement or release?
(describe)
|
No
carbons given off, rearrange-ment only
|
Two
c’s given off as 2CO2
|
4 C’s given off as CO2
|
No more atoms of glucose are left
|
|
- Other?
|
NAD+->
NADH
FADH+ ->
FADH2
(reduction)
|
|
|
NADH -> NAD+
FADH2-> FADH+
(oxidation)
