Pyruvate functions as a substrate for three different catabolic processes, which are characteristic of specific oxygen levels and the type of organism.
a. Identify the three products formed from these three different catabolic processes.
b. For each molecule, identify if they are formed during high oxygen or low oxygen levels
c. For each molecule, identify what type of organism they would be formed in.
Homework Answers
a. Ethanol- Alcoholic fermentation
carbon dioxide, water and ATP- Aerobic Respiration
carbon dioxide, ATP and lactic acid- Anaerobic respiration
b. Ethanol- low oxygen concentration
carbon dioxide, water and ATP- high oxygen concentration
carbon dioxide, ATP and lactic acid- low oxygen concenntration

Contrast the different processes by which a pigment molecule may lose the energy of an absorbed photon. • How is the water that is the byproduct of cellular respiration produced? Which type of DNA repair system can repair errors in double-stranded DNA? Single stranded DNA? • How does the reduction of pyruvate to lactic acid during fermentation allow glycolysis to continue in the absence of oxygen?
