Respiration- the Link Reactions Flashcards
Where do the link reactions take place in the cell?
The matrix of the mitochondrion
What must be available for the link reactions to take place?
oxygen
What first enters the mitochondrial matrix ?
The two pyruvate molecules that were produced during glycolysis must enter the mitochondrial matrix by passing through the outer and inner membranes of the mitochondrion.
What does the link reactions link?
The link reaction links the products of glycolysis with the beginning of the aerobic reactions of Krebs’ Cycle.
What is the name of the reaction that occurs when the pyruvate becomes oxidized by losing H to NAD?
Oxidative decarboxylation
The pyruvate also becomes decarboxylated when it loses what?
Carbon
After the pyruvate is decarboxylated what is it transformed into ?
An acetyl group
After the pyruvate is transformed into an acetyl group, the acetyl group is picked up by?
A carrier molecule called Co enzyme A
The acetyl group and the Co enzyme A react together to form?
Acetyl Co enzyme A
After the formation of the acetyl Co enzyme A, what happens to it?
Acetyl Co enzyme A then enters the Krebs’ Cycle and is necessary for the Krebs’ Cycle reactions to occur.
