According to Reece et al. (2018) enzymes speed up the cell's chemical reactions by lowering energy barriers. What dofs this mean?
A. Enzymes raise the temperature of the reactants to speed up reactions.
B. Enzymes increase the energy barrier, making reactions faster.
C. Enzymes act as catalysts, reducing the amount of energy required for a reaction to occur (activation energy).
D. Enzymes slow down reactions by increasing energy barriers.
