 ANSWERS:

 

Glycolysis

“Step 1 ½”

Kreb’s Cycle

Electron Transport Chain

  1. 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

  1. How much Net ATP is formed at this step?

 

2

0

2

34

  1. Is the ATP formation called oxidative phosphorylation or substrate level phosphorylation?

 

Substrate level

no ATP formed here

Substrate level

Oxidative

  1. 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)

  1. 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)

  1. 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

 

  1. Other? 

 

NAD+->    
             NADH

FADH+ ->
             FADH2
(reduction)

 

 

NADH -> NAD+

FADH2-> FADH+  (oxidation)
