The Transfer of Electrons from Glucose to Oxygen During Aerobic

Multiple Choice

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:

A) it is chemically impossible to transfer electrons directly from glucose to oxygen.
B) the chemical intermediates donate some of their electrons in order to increase the electron pool.
C) the energy of the electrons can be used to make ADP.
D) the energy of the electrons can be used to make ATP.
E) the energy of the protons can be used to make ATP.
