Which of the following best describes what will result when a glucose-fed yeast cell is placed in an anaerobic environment?
Choose 1
The yeast cell will produce ATP through fermentation, generating CO, and ethanol as
byproducts
The yeast cell will produce ATP through fermentation, generating lactic acid as a byproduct
Due to a lack of oxygen the yeast cell will no longer produce ATP, and its ATP stores will be
depleted
Due to the presence of oxygen, the yeast cell will produce ATP through oxidative
phosphorylation

1. an enzyme is considered a(n) because it speeds up a chemical reaction without being used up.2. in a catalyzed reaction, a reactant is often called a(n) . an enzyme is specific because the shape of its matches only particular reactants.4. an enzyme speeds up reactions by lowering the . the between an active site and its substrate often strains bonds and the reaction proceed.6. a( , which is often a vitamin, binds to an enzyme and plays a role in catalysis.7. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity.
