When you hear the word bacteria, what comes to mind

Which enzyme is responsible for “unzipping" the dna by breaking the hydrogen bonds between the nucleotides?

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.

During the final stage of the cell cycle, cytokinesis allows the cell to finish dividing, creating with copies of dna. can someone fill in the blanks?
