Vocabulary
aerobic respiration Cellular respiration in the presence of oxygen.
alcoholic fermentation Fermentation in the absence of oxygen; produces ethyl alcohol
(drinking alcohol) and carbon dioxide; occurs in yeasts.
anaerobic respiration Cellular respiration in the absence of oxygen; fermentation.
ATP A usable form of energy inside the cell; adenosine triphosphate.
cellular respiration The process in which the energy in food is converted into energy that
can be used by the body’s cells; in other words, glucose (and oxygen) is converted into
ATP (and carbon dioxide and water).
citric acid cycle Middle phase of cellular respiration; formation of electron carriers occurs
during this phase; also known as the Kreb’s cycle.
cristae The inner membrane of the mitochondria. The inner membrane of the mitochon-
dria.
