|
Understanding the Terms
A.
The complete breakdown of glucose to carbon dioxide and water with the resulting buildup of 36
ATP.
|
|
|
27.
|
B. Anaerobic breakdown of glucose that results in a gain of 2 ATP and end
products such as alcohol and lactate.
|
|
|
28.
|
C. Anaerobic breakdown of glucose that results in a gain of two ATP and
the end product pyruvate.
|
|
|
29.
|
D. Cycle of reactions in mitochondria that begins with citric acid; it
produces CO2, ATP, NADH, and FADH2; also called the citric acid cycle.
|
|
|
30.
|
E. Metabolic reactions that use the energy from carbohydrates or fatty
acid or amino acid breakdown to produce ATP molecules.
|
|
|
31.
|
F. Metabolites that are the products of and/or the substrates for key
reactions in cells allowing one type molecule to be changed into another type, such as the conversion
of carbohydrates to fats.
|
|
|
32.
|
G. Molecule made up of a two-carbon acetyl group attached to coenzyme A.
During aerobic cellular respiration, the acetyl group enters the Krebs cycle for further
breakdown.
|
|
|
33.
|
H. The use of oxygen to reconvert lactate, which builds up during
anaerobic conditions, to pyruvate.
|
|
|
34.
|
I. Passage of electrons along a series of membrane-bounded carrier
molecules from a higher to lower energy level; the energy released is used for the synthesis of
ATP.
|
|
|
35.
|
J. Coenzyme that delivers electrons from both glycolysis and the Krebs
cycle to the electron transport system during aerobic cellular respiration.
