AAMC FL3 B/B #39

Hello Next Step,

The answer explanation states that succinyl-CoA Synthetase results in the increased production of succinate. I looked up the chemical equation and I see that this is true. My question is, when it comes to the name "succinyl-CoA Synthetase", what part of that suggests it makes succinate?

Here are my thoughts so far: "Synthetase" obviously means you are synthesizing something. Based on that, I know a new substance is being made. I guess it might be the -CoA part that is confusing me. How does that come into play here? Or, does the -CoA even matter?

Thanks,
Justin

Hey Justin,

This is one of those enzymes you should recognize by name just from memory. It catalyzes a step in the Krebs cycle that's associated with producing a GTP and a CoA, and it's fair game on the MCAT to expect you to basically have completely memorized the Krebs cycle.
