Study Guide 2: Cell Respiration Of Carbohydrates:kreb's Cycle

Front 1

Krebs Cycle:

Briefly describe the cycle.

Back 1

A cyclic sequence of reactions, and with each turn 3 significant things occur:

2 CO2's are liberated.
1 ATP is synthesized.
8 electrons are removed forming 3 NADH’s and 1 FADH2.

Front 2

In Kreb's Cycle:

Explain how the carbons of glucose are liberated as CO2.

Back 2

2 CO2's are liberated with the oxidation of the 2 pyruvic acid molecules.

4 CO2's are liberated with 2 turns of the Krebs cycle.

Front 3

In Kreb's Cycle:

How many molecules of ATP are synthesized by substrate phosphorylation for each turn of the cycle?

Back 3

1 ATP.

Front 4

In Kreb's Cycle:

What is the net ATP production per glucose molecule?

Back 4

2 ATP’s.

Front 5

In Kreb's Cycle:

In part of the cell does process occur?

Back 5

In the matrix of the mitochondria.
