Catalyst = peroxide 3. At what approximate temperature do enzymes normally operate in the body of a warm-blooded animal? Would your answer change if the enzyme came from a plant or yeast? Enzymes normally operate in the body of a warm-blooded animal at the range of approximately 75°F - 100°F. If the enzyme came from a plant or yeast it would probably operate at a different temperature. 4. What allows peroxidase to be specific for its substrate?

This process occurs in yeast and bacteria as well as muscle cells that have no oxygen left. In yeast fermentation produces ethyl alcohol and carbon dioxide from glucose and fructose.

stage of alcoholic fermentation the pyruvate splits itself into carbon dioxide and acetaldehyde. NADH is then taken from the acetaldehyde and ethanol is left.

As explained before the carbon dioxide molecules that are given off during the second stage of fermentation caused the dough to rise and the ethanol that was left bakes out of the bread.
