This cycle occurs only in the presence of oxygen. It takes place in the mitochondria.
The oxidation of pyruvic acid into CO2 and water is called Krebs cycle:
Pyruvic acid +CoA --------> Acetyl CoA +CO2. This reaction is catalyzed by a set of enzymes called pyruvic acid dehydrogenase. In this reaction, 2 hydrogen atoms and one CO2 molecule are removed.
The 2 hydrogen atoms are accepted by NAD and NAD is converted into NADH.
Pyruvic acid and CoA are the reactants. The products are 2 H+ and CO2 and Acetyl CoA.
From my Biology book i believe these are the answers
reactants: acetyl CoA
products: CO2, CoA, NAD, NADH+H, ATP, FADH2
pyruvic acid from glycolysis
The Krebs cycle takes place in the matrix of the mitochondria. Pyruvic acids go in and NADH comes out.
most become reactants in the electron transport chain
The Krebs cycle
The citric acid cycle a.k.a. the tricarboxylic acid cycle , the Krebs cycle, or the Szent-Györgyi-Krebs cycle
The Krebs cycle occurs in the matrix of the mitochondrion.
Its Acetyl-CoA
The Krebs cycle is also referred to as the citric acid cycle. Its reactants are pyruvate, NAD+, FAD, acetyl CoA and ADP.
The Krebs cycle takes place in the matrix of the mitochondria. Pyruvic acids go in and NADH comes out.
most become reactants in the electron transport chain
step 3
most become reactants in the electron transport chain
most become reactants in the electron transport chain
most become reactants in the electron transport chain
most become reactants in the electron transport chain
They are the end products of glycolysis. ** ^wrong, in between glycolysis and the kreb's cycle is pyruvic acid oxidation
The Krebs cycle
Krebs cycle.
