Lesson 7: Cellular Respiration - Kreb's Cycle

aerobic

What type of respiration is citric cycle?

mitochondria

where does the citric cycle occur?

Acetyl CoA

what will the pyruvate be transformed into?

first step of pyruvate breakdown

A carboxyl group is removed from pyruvate, releasing carbon dioxide.

second step of pyruvate breakdown

NAD+ is reduced to NADH.

third step of pyruvate breakdown

An acetyl group is transferred to coenzyme A, resulting in the formation of acetyl CoA

oxaloacetate, citrate

In the presence of oxygen, acetyl CoA delivers its acetyl group to a four-carbon molecule, ______, to form ________, a six-carbon molecule with three carboxyl groups

tricarboxylic acid cycle

alternative name for citric acid cycle

matrix of mitochondria

the citric acid cycle takes place in the what?

succinate dehydrogenase

Almost all of the enzymes of the citric acid cycle are soluble, with the single exception of the enzyme ______, which is embedded in the inner membrane of the mitochondrion.

6 NADH, 2 FADH, 2 GTP, 4 CO2

what are the end products of the citric acid cyle?
