1. Name two places(organs or cells) where anaerobic respiration is common.
Skeletal muscles, Red blood cells
Revised: 02/20/09
2. Give a situation which anaerobic respiration is necessary
Anaerobic respiration can occur if activity is so vigorous that cells cannot get oxygen rapidly enough
3. Compare and contrast briefly anaerobic resp. and aerobic respiration.
Aerobic resp.
Anaerobic resp.
O2 need or use
Occur in Mitochondria
The most ATP produced in ETC
Occur in most cells
Produce CO2, H2O,ATPs
Kerbs cycle, ETC
Pyruvic acid enters mitochondrion
O2 don’t need
Occur in cytoplasm
Less ATP produced
Usually occur in skeletal muscles, Red blood cells
Pyruvic acid is converted to lactic acid
Lactic acid path way
4. In aerobic respiration, what molecule will be produced in waste other than ATPs? In anaerobic respiration?
Produce CO2, H2O in aerobic resp.; lactic acid
5. Why can we not survive indefinitely using anaerobic respiration?
Because anaerobic respiration produces not enough APT for body work.
6. What molecule is recycled in anaerobic respiration?
Lactic acid is recycled by converting glucose in the liver. * Think about Cori cycle
7. Name molecules can produce ATP(energy) other than sugars. What are the product names can be used as a
energy and waste produce after producing ATP or energy source?
Protein- Ketone acid(as a energy source), Urea (Waste),
Fat – Keto bodies(as a energy source)
8. Name the pathway before an amino acid (protein) can be used to obtain energy
Oxidative deamination – Remove amine group from amino acid resulting in the formation of Keto acids and urea.
9. Match the term. (one or more.)
Glycolysis
This one pathway takes place in all cells.
Glycolysis, Krebs cycle
In that process, NAD is required and reduced to produce NADH;
Electron transport
produce ATPs by oxidative phosphorylation
Glycolysis, Cori cycle
Break down glucose
Cori cycle
Store sugars as form of glycogen
Electron transport
The most APTs produce in this stage
Cori cycle
In that process Liver has enzyme to produce a form of glucose that can be secreted
into the blood
electron transport
In that process NADH is oxidized to NAD
Krebs cycle, electron transport
Occur in mitochondria
Krebs cycle
These need acetyl-CoA as the input and have two cycles per glucose.
Krebs cycle
Produce CO2 in this pathway.
Cori cycle
Lactic acid is recycled by being converted back to glucose
Krebs cycle
One GTP is produced, from which an ATP is generated
Cori cycle
This process involves skeletal muscle and liver.
Electron transport
In that process ATP is produced by oxidative phosphorylation
Krebs cycle
In that process One FAD is reduced to FADH2
SI Bio6 Dr. Wright’s class
Electron Transport
made by Pyeongsug Kim
Revised: 02/20/09
In that process NADH and FADH2 donate their electrons to the pathway where most
of the ATP is produced
Krebs cycle
After protein and fat are break down and “fed into” this/these pathways.
Electron transport
In that process Oxygen is the final electron acceptor and Water is produced
electron transport
“proton pumps” in the inner mitochondrial membrane are utilized in this pathway
glycolysis
Krebs cycle
electron transport
Cori cycle
10. When cell make ATP or energy, please list in order which one will be chosen to make ATP and which one is later
and the last.
__3__ Protein
__1__ Glucose
__2__ Lipids
11. a. Formation of fat usually occurs in liver and adipose tissue
b. When our body has enough ATPs, glucoses are stored two forms. What are they? Glycogen and Lipids(fat).
c. Free fatty acids is catabolized(broken down) by beta-oxidation for energy
d. Amino acid is catabolized(broken down) by oxidative-deamination for energy
