Which molecule in this reaction is oxidized?
In this reaction, electrons are transferred directly from glucose to oxygen.
In this series of reactions, NAD+ is oxidized.
In aerobic respiration, what is the ultimate fate of the electrons NADH is carrying?
They are transferred to oxygen.
They are transferred to glucose.
They are transferred to water.
They are transferred to ATP.
The letter 'A' in this diagram represents glycolysis.
The letter 'C' could represent oxygen gas.
The process that links 'A' and 'B' produces NADH and carbon dioxide.
Process 'A' involves oxidation-reduction reactions, but process 'B' does not.
The molecule represented by the letter 'D' is most likely carbon dioxide.
The letter 'E' could represent NADH and FADH2.
In the process labeled 'F', ATP is synthesized by substrate-level phosphorylation.
If the thick yellow line in this image represents the mitochondrial membranes, what do 1 and 2 represent?
1 is oxygen and 2 is ATP.
1 is oxygen and 2 is NADH.
1 is carbon dioxide and 2 is ATP.
1 is carbon dioxide and 2 is NADH.
The substance labeled 'A' is most likely an electron.
The region labeled 'C' is the intermembrane space in the mitochondrion.
'A' represents an electron transport chain.
A phosphorylation reaction occurs at 'C'.
'E' most likely represents NADH.
'F' represents the ultimate electron donor in aerobic respiration.
In the absence of oxygen, organisms will break down pyruvate into carbon dioxide and alcohol or lactic acid. These pathways allow for
the production of more ATP than in the presence of oxygen
the regeneration of NAD+ that has been depleted
the oxidation of water to produce needed oxygen molecules
a shift from respiration to photosynthesis in the cell
The ATP generated by glycolysis is produced by
the dephosphorylation of ADP
