Which option is a balanced equation for photosynthesis? a. co2 + h2o > c6h12o6 + o2 b. 6c6h12o6 + 6o2 > 6co2 + h2o c. c6h12o6 + 6o2 > 6co2 + 6h2o d. 6co2 + 6h2o > c6h12o6 + 6o2

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.
