Krebs Cycle Flashcards
What is a synonym for the krebs cycle?
The citric acid cycle and TCA cycle
What is the purpose of the Krebs cycle?
Oxidizing Macronutrients and produces NADH + FADH2 which deliver electrons to the ETS to make ATP
Carbohydrates and Fats enter the Krebs cycle as ____
Acetyl CoA
Carbs enter the krebs cycle after running through ______ and a prep step
Glycolysis
Fats can enter the krebs cycle after running through ___ _____
beta oxidation
Pyruvate becomes Acetyl CoA utilizing _______
Pyruvate dehydrogenase complex
The reaction in which pyruvate becomes Acteyl CoA (dehydrogenation) is _______ and happens within the mitochondrial matrix
irreversible
What is Beta Oxidation?
oxidation of fatty acids where a two carbon molecule (acetyl CoA) is cleaved off the fatty acid
Where does Beta Oxidation happen?
Happens within the mitochondrial matrix
What is the universal carrier of Acyl groups ?
Coenzyme A
This coenzyme consists of pantothenic acid (B5) and a terminal thiol (SH) group and forms high-energy thioester bonds with acetic acid (acetyl CoA) and fatty acids (acyl CoA)
Coenzyme A
This coenzyme is Used in fatty acid synthesis and oxidation, pyruvate oxidation and acetylation
Coenzyme A
Which one is the acetyl CoA?

Acetyl CoA and Oxaloacetate utilize this enzyme in order to become citric acidd
citrate synthase
What enzyme is utilized during isomerization in Krebs Cycle? Specifically in thereaction that transfomrs Citric acid to isocitric acid
Aconitase
What is the enzyme utilized in the reaction which Isocitric Acid becomes Oxalosuccinate and later Alphaketoglurate?
Isocitrate dehydrogenase
