Содержание слайда: The Krebs cycle
The Krebs cycle (also known as the citric acid cycle or tricarboxylic acid cycle) was discovered in 1937 by Hans Krebs.
The Krebs cycle is a closed pathway of enzyme controlled reactions.
■Acetyl coenzyme A combines with a four-carbon compound (oxaloacetate) to form a six-carbon compound (citrate).
■The citrate is decarboxylated and dehydrogenated in a series of steps, to yield carbon dioxide, which is given off as a waste gas, and hydrogens which are accepted by the carriers NAD and FAD.
■Oxaloacetate is regenerated to combine with another acetyl coenzyme A.

Содержание слайда: the Krebs cycle
• Two molecules of carbon dioxide are given off in separate decarboxylation reactions.
• A molecule of ATP is formed as part 1 of the reactions of the cycle - as with glycolysis, this ATP synthesis is 'at substrate level' too.
• Three molecules of reduced NAD are formed.
• One molecule of another hydrogen accepter - FAD (flavin adenine dinucleotide) is reduced. (NAD is the chief hydrogen- carrying coenzyme of respiration but FAD is another coenzyme with this role in the Krebs cycle).
