Kreb's Cycle

The Kreb’s cycle occurs in the ——

mitoochondria, in the spaces around the cristae.

The pyruvates are made_

in glycolosis and are shuttled into the mitochondria with a transport proteins.

The purpose of the Kreb’s cycle is…

to make electron carriers to be used in the electron transport chain.

Carbon Dioxide is…

a byproduct of this step.

In order for the 2 carbon molecule known as ___ to enter the Kreb’s Cycle ___ must bond to it

Acetate, Coenzyme A (CoA)

When acetate and coenzyme A bond…

it forms Acetyl CoA

As soon as acetate enter the cycle, .

Coenzyme A detaches and is ready for another acetate

For 1 pyruvate

1 ATP, 4 NADH, 1 FADH2, and 3 CO2

For 2 pyruvates

2 ATP, 8 NADH, 2 FADH2, and 6 CO2The

Kreb’s cycle must turn ___ to break down both the pyruvates made in glycosis, so to break down one glucose molcules the cycle turn ___

twice, twice
