a researcher proposes a model of an enzyme catalyzed reaction in which reactant is converted to a product. The model is based on the idea that the reactant passes through a transition state within the enzyme substrate complex before the reactant is converted to the product. which of the following statements best helps explain how the enzyme speeds up the reaction ?

The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.

Explanation:

Enzymes are complex multi-folded forms of proteins - they promote chemical reactions in biological processes.

Typically, molecules collide at random, and complex chemical reactions require the right molecular orientation and energy to react (breaking and forming bonds).

Enzymes lower energy needs by providing an alternative reaction pathway and stabilize and maintain the molecules in their intermediate forms called transition states.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
