Detailed explanation-1: -This statement about enzymes is true: Enzymes accelerate reactions by lowering the activation energy. Enzymes are proteins whose three-dimensional form is key to their function. Enzymes do not alter the overall change in free energy for a reaction.
Detailed explanation-2: -According to the most widely accepted theory, enzymes bind to the substrate molecule and form a transition state.
Detailed explanation-3: -Enzymes speed up chemical reactions. Enzymes react best at a specific temperature. Enzymes only control ONE type of reaction.
Detailed explanation-4: -Features of Enzyme Catalyzed Reactions Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
