Key Vocabulary Words:
1) Cell Respiration: The controlled release of energy in the form of ATP from organic
compounds in cells
2) ATPase: The enzyme needed to catalyse the hydrolysis reaction of ATP breaking
down into ADP and releasing 30.7kJ of energy
3) Phosphorylation: The process of adding a phosphate group to ADP (to synthesise
ATP)
4) Glycolysis: In cell respiration, glucose in the cytoplasm breaks down into pyruvate
(three-carbon compound) with a small yield of ATP
5) Anaerobic Respiration: Respiration without using oxygen; Pyruvate in the
cytoplasm is either converted into lactate (in humans) or ethanol and carbon
dioxide (in yeast), with no yield of ATP
6) Aerobic Respiration: Respiration using oxygen; Pyruvate in the mitochondria
breaks down into carbon dioxide and water with a large yield of ATP.
7) Lactic Fermentation: Pyruvate breaks down into lactate (lactic acid) in humans - in
anaerobic respiration
8) Alcohol Fermentation: Pyruvate breaks down into alcohol and carbon dioxide in
yeast - in anaerobic respiration
*Remember, cellular respiration is not the same as breathing*
Cellular respiration is the controlled release of energy from organic compounds in cells
to from ATP.

2. Jessie, Diego, Ting-Ting, Mychi
Aerobic respiration occurs in the presence of oxygen. Reactions continue in the
mitochondria.
Anaerobic respiration occurs in the absence of oxygen
