This class might actually kill me

Today my Animal Physiology professor told us that the ideal gas constant (R) is different for every gas. She said there’d probably be a table in our textbook listing all the different gases and their respective gas constants, which is untrue because IT’S COMPLETELY WRONG. This, combined with the fact that our notes are fill-in-the-blank and her overuse of the phrase “of course” (And, of course, mitochondria consume oxygen, which of course produces ATP. This is of course called mitochondrial respiration), has caused me to question absolutely everything she says because she’s probably wrong about it. Good thing our exams are straight-forward textbook memorization or I’d be screwed!
