Q: enzyme
Answer:
a protein that functions as a catalyst to accelerate the rate of a chemical reaction;
enzymes are critical in determining which chemical reactions take place in a cell
Q: transition state
Answer:
the brief time in a chemical reaction in which chemical bonds in the
reactants are broken and new bonds in the product are formed
Q: activation energy
Answer:
the energy input necessary to reach the transition state
Q: substrate
Answer:
a molecule acted upon by an enzyme
