What is the fate of the radioactive label when each of the following compounds is added to a cell extract containing the enzymes and cofactors of the citric acid cycle and the pyruvate dehydrogenase complex?
Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.

P.S. A detailed steps explaination would be greatly appreciated. Also, any tips on how to solve such problems if possible? Is there any particular fate that C atoms of the R group for example, have, at the end of the cycle? I usually think of drawing out each step and solving but I believe that there must be a shorter, smarter way to do it and similar questions. Thank you!
