During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a ∆g of -20 kcal/mol. if you double the amount of enzyme in the reaction, what will be the ∆g for the new reaction?
a) -40 kcal/mol
b) -20 kcal/mol
c) 0 kcal/mol
d) +20 kcal/mol

The correct answer is: B) -20 kcal/mol

Enzymes are catalysts of chemical reactions, they speed up the reaction by lowering the activation energy, but don't affect the ∆G (change of Gibbs free energy). The changes in free energy occurs due to change in concentrations of reactants and products and don't have anything to do with the presence or absence of an enzyme.

i think the answer would d

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
