• Use light to split water into oxygen and hydrogen ions

• make NADP+ into NADPH

Why is oxygen necessary in cellular respiration?

• It splits glucose

• It makes ATP

• It is the final electron acceptor

• It isn't, oxygen is a conspiracy created by the government to trick people into thinking that trees are good so they can install microphones and cameras in trees everywhere to monitor us every chance they get... death to trees!

Matt got fired from his nursing job because he hooked up distilled water to someone's IV instead of saline. Why was the hospital right to fire him?

• The blood cells shrank and died because the drip was a hypertonic solution

• The blood cells became swollen and lysed because the drip was a hypotonic solution

• The water increased the volume of blood and the heart had to work harder to compensate and the patient's breathing slowed down.

• Matt was too good for that job anyway. Who even wants to save lives for a living?

The point of the Krebs Cycle is to...

• Produce high amounts of ATP using a proton gradient

• Move high energy electrons through series of proteins to eventually bind with O₂, creating water and protons

• Break down pyruvate to produce electron carrier molecules, FADH₂ and NADH, as well as CO₂ and ATP as byproducts

• Use ATP and NADPH to produce 6 carbon sugars
