a.
Glycolysis releases less than a quarter of the chemical energy in glucose that can be released by cells; most of the energy remains in__
the two molecules of pyruvate
i.
With molecular oxygen,what does pyruvate do?
ii.
Glycolysis produces __net ATP molecules
the pyruvate enters a mitochondrion, where the oxidation of glucose is completed
two
a.
Pyruvate enters mitochondria (__transport)
à
converted to __
active
acetyl CoA
The conversion of pyruvate serves what purpose?
links glycolysis and the CAC and is carried out by a multienzyme complex in three steps
What are the three steps of the linker reaction?
1.
Pyruvate’s carboxyl group, which is already fully oxidized and has little chemical energy, is removed and given off as a molecule of CO
2
2.
The remaining two- carbon fragment is oxidized, forming acetate. The extracted electrons are transferred to NAD
+
, storing energy in NADH
3.
Coenzyme A is attached via its sulfur atom to acetate, forming acetyl CoA
Is the linker reaction exergonic or endergonic?
exergonic
