Detailed explanation-1: -The answer is enzymes. 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.
Detailed explanation-2: -The statement is True. The statement is correct because enzymes significantly enhance the speed of chemical reactions and thus bind with the substrate or reactant molecules to form the product. They serve as biological catalysts that typically reduce the activation energy so that the product can be formed faster.
Detailed explanation-3: -Answer and Explanation: The following statement, “Enzymes are catalysts and appear unchanged at the end of the reaction, ‘’ is true. Enzymes speed up, or catalyze the rate of a chemical reaction by lowering the activation energy of the reaction itself.
