The purpose of the Krebs cycle is to

• completely oxidize the remaining carbon chain

• produce carbon dioxide

• produce water

• regenerate NAD+ so glycolysis can continue

Chemiosmosis is the use of energy to _______________________

• set up a hydrogen ion gradient

• set up an osmotic gradient

• attach a phosphate onto an ADP

• remove electrons from the ETC using oxygen gas

What is FALSE about ATP synthase

• it can be found in the mitochodrion and chloroplast

• it is an enzyme with two substrates, ADP and a phosphate

• it is a transport protein

• it actively transports H+ across membranes

Oxygen gas is a _____________ of cell respiration because it _______

• reactant, replaces lost electrons from glucose

• reactant, removes low energy electrons from the ETC chain

• product, it the left over after the carbon chain releases its electrons

• product, when water splits to give electrons, oxygen gas is the waste product
