Question
Chapter 24.7, Problem 13P
Interpretation Introduction
Interpretation:
The name of coenzyme involved in pyruvate to acetaldehyde conversion should be determined.
Concept introduction:
Glycolysis: It is pathway which describes conversion of one molecule of glucose into 2
molecules. It involves totally 10 set of reactions with it.
Substrate: The molecule where the reaction takes place with help of enzymes.
Coenzyme: They are non-proteins molecules which helps enzymes for catalyzing the reaction.
Enzyme: The proteins that helps
Oxidation: The oxidation is reaction that involves addition of oxygen atom or loss of electrons or removal of hydrogen atom present in the chemical compound.
Reduction: It involves removal of oxygen or addition of hydrogen to the chemical compound.

What coenzyme is required to convert pyruvate to acetaldehyde?
Pyruvate is a precursor for which of the following molecules?
ethanol
O acetyl-CoA
O glucose
oxaloacetate
O lactate
Question 5
Which of the following cofactors participate in both glycolysis and the citric acid cycle?
ATP
O NAD+
GTP
acetylCoA
O NADP+
Most fatty acids have an even number of carbons and, therefore, are completely metabolized to acetyl-CoA. A fatty acid with an odd number of carbons is metabolized to acetyl-CoA and one equivalent of propionyl-CoA. The following two reactions convert propionyl-CoA into succinyl-CoA, a citric acid cycle intermediate, so it can be further metabolized. Each of the reactions requires a coenzyme. Identify the coenzyme for each step. From what vitamins are the coenzymes derived?
