phosphorylation? Ans: 34 ATP
What is the rate limiting step of glycolysis? Ans:
Guru01 - Stuvia
Phosphofructokinase-1 (PFK-1)
Expert
What is the rate limiting step of TCA cycle? Ans: isocitrate
dehydrogenase
What is the rate limiting step of oxidative phosphorylation?
Ans: Cytochrome C Oxidase (Complex IV)
What is glycolysis? Ans: the breakdown of glucose by
enzymes, releasing energy and pyruvic acid.
What is the TCA cycle? Ans: a series of metabolic reactions
that break down molecules of acetyl CoA to generate carbon
dioxide , energy and reducing agents
What is oxidative phosphorylation? Ans: process that uses
oxygen and high=-energy electrons to produce ATP and water.
What are the allosteric regulators in glycolysis? Ans: -
Positive: AMP, Fructose 2,6 Bisphosphate, Fructose 1,6
Bisphosphate
, 3
-Negative: Glucose-6 phosphate (G6P), ATP, Citrate
What are the allosteric regulators in the TCA cycle? Ans: -
Positive: ADP, Ca2
-Negative: NADH
What are the regulators in oxidative phosphorylation? Ans: -
Positive: ADP

What is the ETC? Ans: Series of proteins embedded in the
inner membrane of the mitochondria. They pass down high E
electrons from one protein to the next, using the energy of the
Guru01 - Stuvia
electron to pump protons into the inter membrane space.
Expert
Leaving the intermembrane space with a low pH.
What enzyme traps glucose inside the cell, committing it to
metabolism? Ans: Hexokinase
What is the only TCA cycle enzyme that is bound to the
mitochondrial membrane instead of soluble in the
mitochondrial matrix? Ans: Succinate Dehydrogenase
What is the step that links glycolysis to the TCA cycle? Ans:
Oxidation of Pyruvate to Acetyl CoA
What enzyme is in charge of aerobic pyruvate oxidation? Ans:
