Bio PreComp The Citric Acid Cycle Cellular Respiration

Where is the Krebs Cycle

Mitochondrial Matrix

What is the Krebs Cycle oxygen requirements

Aerobic

How many reactions occur in Krebs Cycle

11 enzyme mediated reactions

Products of Citric Acid Cycle

2 ATP, 8 NADH, 2 FADH2, 6CO2

Pyruvate Oxidation right before the C.A.C Explanation

2 pyruvate oxidized to 2 molecules of Acetyl-CoA, A pyruvate takes NAD+ and makes NADH and a carbon is cleaved from pyruvate and released as CO2, then make Acetate, CoA is made using Coenzyme A

Citric Acid Cycle explanation

CoA bonds to oxaloacetate, forming citric acid which will then be oxidized. A carbon is cleaved and makes Carbon, NADH is produced/ reduced and Citric Acid a-Ketoglutaric Acid, another Carbon is cleaved and anothe NADH is produced as well as ATP, Aketo turns into Succinate and FADH is produced/reduced alongside NADH, Succinate then becomes a oxaloate

How many times does the C.A.C happen

twice, once for each pyruvate

Glycolysis and C.A.C produce

6 ATP, 10 NADH, 2FADH2, 6 CO2
