Cell respiration
Cell respiration is most accurately described as a ____ process
The energy of the electrons can be used to make ATP
The transfer of electrons from glucose to oxygen during aerobic respiration takes place in a stepwise fashion through a number of intermediates rather than by direct transfer. This is because
The splitting of molecules into smaller components is referred to as _______
Anabolic reaction
are generally endergonic, usually require ATP, are part of metabolism, may produce polysaccarides from monosaccharides.
Redox process (Reduction and Oxidation)
Aerobic respiation is classified as______
Electrons; proton
During chemiosmosis ________ are transferred from NADH and FADH2 to electron acceptor molecules, and the nergy released is used to create a __________
C6H12O6 + 6O2 + 6H20 -> 6CO2 +12H2O + energy
Overall reaction for the aerobic reaction of glucose is summarised as

Oxygen in a series of steps
In aerobic respiration, the electrons associated with the hydrogen atoms in glucose are transferred to
In eukaryotes, glycolysis occurs in the
IN glycolysis, a six-carbon glucose molecule is converted to two three-carbon molecules of _______
Glycolysis yields a net energy profit of ____ ATP molecules per molecule of glucose.
ATP synthase
In chemiosmosis, ATP is produced as hydrogen ions (protons) pass through:
Considering only glycolysis and the conversion of pyruvate molecules to acetyl CoA molecules, how many NADH molecules will be produced from one glucose molecule?
1ATP, 3 NADH, and 1 FADH2
During the citric acid cycle, each acetyl group entering the cycle yields.
4CO2 + 6NADH +2FADH2 + 2 ATP
IN the citric acid cylce, two acetyl CoA molecule are metabolized to
The citric acid cycle
A glucose molecule that is metabolized via aerobic respiration has been completely broken down and released as CO2 by the end of
The proton gradient established during electron transport is a form of potential energy
Which of the following statements about the electron transport chain is true?
When hydrogen ions (protons) are pumped across the inner mitochondrial membrane, they form a proton gradient. ATP is then formed by a process knwon as:
ATP is produced by phosphrylation of ADP
Chemiosmosis allows exergonic redox processes to drive the endergonic reaction in which:
THe role of the oxygen molecules required for aerobic respiration is
to accept the low energy electrons at the end of the electron transport chain.
