Enzymes work best at a specified pH.

. Generally an enzyme is specific for a substrate. - They are regulated by positive and negative modulators - They have more than one native conformation - Their activity is altered by phosphorylation - They often catalyse a reaction at the beginning of a metabolic pathway. Enzymes are composed primarily of carbohydrates.

According to the most widely accepted theory enzymes bind to the substrate molecule and form a transition state. The function of an enzyme is to speed up chemical reactions that occur in your body. Enzymes prevent changes in substrate concentrations from having an effect on reaction.

Which of the following statements about enzymes is true.

The activity of the enzyme is also affected by phosphorylation. Which of the following statements is not true about cytochrome P450 enzymes. They lower the energy of activation for a reaction.

They are consumed by the reactions they catalyze. Enzymes do not alter the overall change in free energy for a reaction II. Enzymes increase reaction rates.

Enzymes alter the chemical composition of the products of a reaction. The other given statements are true. A Enzymes themselves change during each reaction and thus can only be used by the body a single time.
