Question

Use complete sentences to explain how an enzyme helps an organism.

Use the words: reaction and energy​

Answer 1

Enzymes can be taken as biological and chemical catalysts which are proteins in biology and certain chemicals in chemistry.

They lower the activation energy in chemistry and in biology the speed up the chemical reaction while leaving the active site the same and they can be used again. Eg:- Amylase, protease, lipase are a few examples in biology and in chemistry there is iron, Vanadium(v) oxide and much more.

Hope this helps :D

Answer 2

Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.
