Some Enzymes Lower Activation Energy by ____

Question

Some enzymes lower activation energy by ____.  
A) keeping substrates apart
B) orienting substrates randomly
C) breaking the laws of thermodynamics
D) shutting out water molecules
E) physically breaking chemical bonds

Accepted Answer

Enzymes lower activation energy primarily by orienting substrates correctly, facilitating the chemical reaction. They do not keep substrates apart, orient them randomly, break the laws of thermodynamics, or physically break chemical bonds without input of energy. Shutting out water molecules can be a mechanism for some enzymes to lower activation energy by creating an environment more conducive to the reaction.
