Acetyl Co-$A$ reacts with . . . . . . to begin Krebs cycle.

The Krebs cycle starts with the formation of a six-carbon compound by the reaction between:

In a single Krebs cycle,decarboxylation takes place at how many steps?

In the following reaction,identify $X$ and $Y$ respectively.
$\text{Pyruvic acid} + \text{CoA} + \text{NAD}^+ \xrightarrow[X]{\text{Mg}^{2+}} Y + \text{CO}_2 + \text{NADH} + \text{H}^+$

The enzyme mediating the reactions of the $Krebs$ cycle during cellular respiration in animals is found in:

In Krebs cycle,$FAD$ participates as an electron acceptor during the conversion of......
