During glycolysis, what is the net production of ATP per glucose molecule?

2

The greatest contributor of electrons to the electron transport chain is...

the citric acid cycle

The oxygen required by cellular respiration is reduced and becomes part of which molecule?

H2O

Fermentation is primarily involved in the recycling of...

NAD+

which of these is not true regarding the citric acid cycle? a) the citric acid cycle includes the prep reaction b) citric acid cycle produces ATP by subtrate-​level ATP synthesis c) citric acid cycle occurs in the mitochondria d) citric acid cycle produces 2 ATP per glucose molecule

a) the citric acid cycle includes the prep reaction

Which of these is NOT true regarding the electron transport chain? a) The electron transport chain is located on the cristae of the mitrochondri​a b) The electron transport chain produces more NADH than any metabolic pathway c) The electron transport chain contains cytochrome molecules d) The electron transport chain ends when oxygen accepts electrons

b) The electron transport chain produces more NADH than any metabolic pathway

Which of these is INCORRECT regarding fermentation? a) there is a net gain of only 2 ATP per glucose b) it occurs in the cytoplasm c) the process starts with glucose entering glycolysis d) NADH donates electrons to the electron transport chain e) it is anaerobic

d) NADH donates electrons to the electron transport chain

Which of the following is not a product or reactant of glycolysis? a) NADH b) ATP c) pyruvate d) oxygen

d) oxygen
