Enzymes decrease the activation energy for a reaction, which allows it to go faster. They usually act by bringing molecules together and encouraging them to react, and they are not broken down in the process.

A. is correct. An enzyme speeds up the rate of chemical reactions in living organisms

Like all catalysts, enzymes work by lowering the activation energy (ÎG‡) for a reaction, thus dramatically accelerating the rate of the reaction.
That would be choice a

Enzymes are biological catalysts, or chemicals that speed up the rate of reaction between substances without themselves being consumed in the reaction.
thefore the answer is "A"

a: it causes chemical reactions to go faster.
Basically, enzymes catalyze reactions, often driving them forward when they would hardly go at all, sometimes using paired reactions to make higher-energy products. (That would usually be hydrolizing ATP to AMP as an energy source; the net reaction goes "downhill" energetically, but the molecule being modified might go "uphill")
