Where does the CO2 humans exhale come from?

• photosynthesis

• it forms between the membranes of the mitochondria during the ETC

• it is made during glycolysis

• its a waste product of the citric acid cycle

Why would somebody not be able to survive much more than a few minutes without oxygen?

• Our supply of ATP runs out in a couple of minutes

• We cannot produce glucose without oxygen

• oxygen makes our cells hypertonic so they would shrivel in a few minutes

• Only our blood needs oxygen. Blood dies very quickly without it.

How exactly does oxygen we breathe help make ATP?

• Helps splits glucose

• It flows through ATP synthase

• Helps pull electrons down the transport chain

Select all of the true statements

• Humans make ATP from both glycolysis and the ETC

• The ETC makes way more ATP than glycolysis

• Humans don't do glycolysis since the ETC is more efficient

• The Citric acid cycle and ETC occur in the mitochondria
