Cellular Respiration Review Sheet
Try to complete as much as possible WITHOUT looking at your notes. Then use your notes to fill in any gaps!
Part A; Overview of Cellular Respiration
Write the equation for cellular respiration.
C6H12O6 + 6O2 -------------------> 6CO2 + 6H2O + ATP

2__C___
Molecule invested to energize glucose at the start of the process
C
ATP
3__B___

D
NAD+
4__F___
‘splitting of sugar’
E
Glucose
5__A___
Carries H and e- from oxidation of glucose
F
Glycolysis
6__G___
Assembled to make ATP
G
ADP and P
7__H___
Not involved in glycolysis
H
Oxygen
Part C: Fill in the blanks to review the grooming of Acetyl CoA and the Kreb Cycle
1. Glycolysis occurs in the

while the Kreb cycle in the
2. While the pyruvate passes into the mitochondria it is converted into
3. As glucose is broken down, bonds are broken and energy is
acetyl CoA
released
4. During these stages of cellular respiration, the Carbon in glucose is released as
5. Some of the energy is released as
ATP
6. The high-energy electrons are carried by
inner membrane of the mitochondria.

Part E: Next to each statement write a G for Glycolysis, KC for Kreb Cycle or ETC for Electron
Transport Chain / Chemiosmosis & Oxidative Phosphorylation
1 __ETC___
Generates most of the ATP formed by cellular respiration.
2__KC___
Reduces NAD+ and FAD, producing NADH and FADH2
3__G___
Occurs outside the mitochondrion.
4__G___
Requires 2 ATP and produces 4 for a net gain of 2 ATP.
5__ETC___
Here e- and H+ combine with O2 to make water.
6__ETC___
Occurs along the inner mitochondrial membrane.
7__KC___
Generates most of the CO2 produced by cellular respiration.
8__ETC___
ATP synthase makes ATP.
Part F: Fill in the blank to review anaerobic respiration.
1. When oxygen is scarce, human muscle cells can make ATP by lactic acid fermentation.
2. Fermentation enables cells to make ATP in the absence of Oxygen.
3. The products of alcoholic fermentation are Ethanol and CO2.
4. Like aerobic respiration, alcoholic fermentation produces CO2
5. The ATP yield of fermentation is much
6. The buildup of lactic acid
