Which of the following is an example of how enzymes are catalyst? a)Enzymes can alter the free energy change (ΔG) for a chemical reaction.

b)Enzymes increase the free energy of the reactants to make the reaction go faster.

c)Enzymes provide the activation energy for the reactions they facilitate.

d)Enzymes lower the activation energy so that reactants absorb enough energy to reach transition state.

geologic time scale (for gradpoint) =)

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )
