1st step is…

removal of carboxyl group from pyruvate, turning it into an acetyl group (C = O w/ CH3)

<p>removal of carboxyl group from pyruvate, turning it into an acetyl group (C = O w/ CH<sub>3</sub>)</p><p></p>

2nd step is…

acetyl group turns into acetyl-coA

<p>acetyl group turns into acetyl-coA</p>

Net gain (per 1 glucose/2 pyruvate)

  • 2 NADH

  • 2 CO2

  • 2 acetyl-coA

net and total gain is the same

What is pyruvate dehydrogenase complex?

3 enzymes that turn pyruvate into acetyl-coA

  • 1st enzyme releases CO2

  • 2nd enzyme puts in Co-A

  • 3rd enzyme reduces NAD+
