18 Questions
What is the product of beta oxidation of fatty acids?
Acetyl CoA, NADH, and QH2
How many ATP molecules can be generated from one acetyl CoA molecule?
10 ATP
What is the final electron acceptor in the electron transport chain?
Oxygen gas
How many rounds of the Krebs Cycle can one molecule of glucose drive?
Two rounds
What is the energy currency of the cell that is generated in the electron transport chain?
ATP
What is the name of the cycle where acetyl CoA is fed and ATP is generated?
Krebs Cycle
What is the reduced form of coenzyme Q?
QH2
What is produced during the breakdown of glucose in glycolysis?
Both ATP and NADH
What happens to pyruvic acid under anaerobic conditions?
It is reduced to lactic acid
What is the purpose of the electron transport chain?
To synthesize ATP
What is the end product of beta oxidation?
Acetyl CoA
What is the energized form of NAD that can feed into the electron transport chain?
NADH
What is the primary function of coenzyme A in metabolism?
To shuttle carbons from glucose and fatty acids into the Krebs Cycle
What is the significance of the sulfur atom in a thioester functional group?
It reduces the strength of the carbon-sulfur bond compared to a carbon-oxygen bond
What happens to the energy state of a molecule when it is reduced by adding bonds to hydrogen?
It becomes a higher-energy compound
What is the role of NAD+ in redox reactions?
It is an oxidizing agent
What is the result of the reduction reaction of NAD+?
NADH is formed with the addition of hydrogen
Why are reduced species often high-energy compounds?
Because they react exothermically with oxygen
Learn about beta oxidation, the process that breaks down fatty acids into two-carbon fragments, producing acetyl CoA, NADH, and QH2. Understand how the chain is cleaved and the resulting products.
