Which of the following is true about enzymes? A:They increase the activation energy which will speed up product production

B:They lower activation energy which will speed up product production.

C:They are checkpoints to make sure the reaction is going smoothly.

D:They decrease the speed of the reaction to make sure that errors are not made.

I believe it's B because they speed up reactions by lowering activation energy. A is incorrect its just similar but diff.

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you

Centration is the correct answer
