2. Enzymes can act as organic catalysts in living things. How do enzymes affect reaction rates in cells? A They slow down cellular reactions by inhibition.
B They speed up cellular reactions by providing a site for substrates to react.
C They speed up cellular reactions by providing energy to the reactants.
D They slow down cellular reactions by lowering the reaction temperature.​

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
