Anaerobic respiration using as the terminal electron acceptor
B
Lactic acid fermentation (anaerobic)
C
Aerobic respiration (using as the terminal electron acceptor)
D
Alcoholic fermentation (anaerobic)
Verified step by step guidance1
Understand that cellular respiration involves the breakdown of glucose to produce ATP, the energy currency of the cell.
Recognize that the efficiency of ATP production depends on the terminal electron acceptor used in the electron transport chain.
Recall that aerobic respiration uses oxygen (O\_2) as the terminal electron acceptor, which allows for complete oxidation of glucose and yields the highest ATP output.
Compare this to anaerobic respiration and fermentation processes, which use other electron acceptors or no electron transport chain, resulting in less ATP per glucose molecule.
Conclude that aerobic respiration produces the most ATP per molecule of glucose under typical conditions because oxygen is a highly efficient terminal electron acceptor.
