Why is ATP, not glucose, the cell's immediate energy source?
Answer: One hydrolysis step releases a small, usable amount of energy
How does the ATP yield of anaerobic respiration compare to aerobic respiration?
Answer: Much lower (2 vs about 30 ATP per glucose)

Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options are other answers from the same set.
