An exergonic chemical reaction
A) converts substrates into products that have more free energy.
B) releases energy as the reaction progresses.
C) requires the input of energy.
D) requires an enzyme in order to overcome the activation energy.

Question

Quizplus · Accepted Answer

An exergonic chemical reaction releases energy as the reaction progresses. In these reactions, the products have less free energy than the substrates. Option A is incorrect because the products have less free energy than the substrates, not more. Option C is incorrect because exergonic reactions do not require an input of energy, they release energy. Option D is incorrect because enzymes lower the activation energy required for a reaction to proceed, but they are not necessary for exergonic reactions to occur.
