Concept explainers
(a)
Interpretation:
The step involved in the citric acid cycle having a reaction which generates NADH needs to be determined.
Concept Introduction:
The citric acid cycle is an eight steps cycle that consists of enzyme-catalyzed reactions that occur in mitochondria. The citric acid cycle starts with the addition of 2 carbon acetyl CoA molecules to four carbon substrates. Acetyl CoA is regenerated at the end of the cycle.
(b)
Interpretation:
The step involved in the citric acid cycle in which CO2 is removed needs to be determined.
Concept Introduction:
The citric acid cycle is an eight steps cycle that consists of enzyme-catalyzed reactions that occur in mitochondria. The citric acid cycle starts with the addition of 2 carbon acetyl CoA molecules to four carbon substrates. Acetyl CoA is regenerated at the end of the cycle.
(c)
Interpretation:
The step involved in the citric acid cycle having the reactions which utilize FAD needs to be determined.
Concept Introduction:
The citric acid cycle is an eight steps cycle that consists of enzyme-catalyzed reactions that occur in mitochondria. The citric acid cycle starts with the addition of 2 carbon acetyl CoA molecules to four carbon substrates. Acetyl CoA is regenerated at the end of the cycle.
(d)
Interpretation:
The step involved in the citric acid cycle having the reaction which forms a new carbon-carbon single bond should be given.
Concept Introduction:
The citric acid cycle is an eight steps cycle that consists of enzyme-catalyzed reactions that occur in mitochondria. The citric acid cycle starts with the addition of 2 carbon acetyl CoA molecules to four carbon substrates. Acetyl CoA is regenerated at the end of the cycle.
