In this lesson, we learned how some cells and organisms perform (a)   cellular respiration, or a process that converts food into energy without (b)   . Oxygen is normally the final electron (c)   in the electron transport chain. Without oxygen, these cells only undergo (d)   and produce 2 ATP per glucose molecule. Next, they need to reduce (e)   to regenerate NAD+ from NADH + H+.

• anaerobic
• oxygen
• acceptor
• glycolysis
• pyruvate

Fermentation is the process that performs this job. In (a)   fermentation, pyruvate is reduced to (b)   . This occurs in cells, such as our (c)   , when we're exercising. In (d)   fermentation, pyruvate is reduced to alcohol and releases (e)   . This type of fermentation is commonly used with yeast to make alcoholic beverages and cause bread to rise.

• lactic acid
• muscles
• alcoholic
