d. Are involved in all of the above

A reduced molecule ______.

a. Has gained electrons

b. Has become more positive in charge

c. Has lost electrons

d. Is an electron donor

Oxidation is the _________________________, and reduction is the _________________________.

An electron carrier before it harvests energy from glucose molecules in a series of gradual steps is:

NADH is commonly used as an electron carrier during the breaking down of complex molecules like glucose in cellular respiration. NADPH is also a common electron carrier. However, NADPH is used to build complex molecules like glucose in a process called:

Which electron carrier is not matched with its correct function?

Define oxidation-reduction, and differentiate the following terms:

a. Aerobic and anaerobic respiration

b. Respiration and fermentation

c. Cyclic and noncyclic photophosphorylation
