Pteridine? Isn't that what they use to power the warp drive on the Enterprise?

Oh, I see. So it's not used for warp drives, but for coenzyme activity.

Pteridine, huh? Sounds like something straight out of a sci-fi novel. But I suppose it's the right answer.

I thought it was the purine ring, but I guess I was mistaken. The pteridine ring makes more sense.

I'm not sure, but I think it might be E) pyridine ring. Can someone explain why it's not the pyridine ring?

I agree with Shala, because folic acid's coenzyme activity is indeed based on the pteridine ring.
