You know your prof is really horrendous at their job when you feel completely panicked about the midterm until you read through the textbook and go "Oh... this is easy." It takes skill to make something as logical as physics so incredibly confusing in class.
"If you were to ask friends and family what carbohydrates do in your body, they would probably say something like "They give you energy." And you'd agree, but only after pointing out that carbohydrates are also used in cell identity, as a structural material, and as a source of carbon atoms for the synthesis of other complex molecules."
And this ^^^ is why you don't have any friends, Karen.
