1 Which of the following does not affect the activity of an enzyme. This shape is determined by the sequence of amino acids held together by bonds for. Speed up chemical reactions.

Also which of the following is characteristic of an enzyme. A They lower the energy of activation of a reaction by binding the substrate. Which of the following properties is not a characteristic of enzymes.

It has a three-dimensional shape. Each has a specific substrate. Enzymes are proteins and therefore are folded chains of amino acids with a specific shape.

CAn enzyme is unchanged as a result of a reaction. Enzymes reduce the activation energy of the reaction they catalyze. The enzyme has a specific substrate that will fit perfectly into the active site and cause a chemical reaction.

View answer additonal benefits from the. Enzymes are biological catalysts. They are affected by temperature.

Which of the following is not a characteristic of enzymes. It plays a role in increasing the energy of activation of the reaction being catalyzed. Characteristics of an Enzyme.

Each is used to break down substances. Extremely high temperatures on the other hand can denature an enzyme causing it to lose its function. D They react chemically with the substrate and gradually get used up in the process.

5 Which of the following is not a characteristic of enzyme. Enzyme activity is slowed when the pH is changed outside of this range. Enzymes alter the equilibrium distribution of the substrate s and product s of the reaction they catalyze.

Enzymes theoretically stabilize the transition state of the reaction they catalyze. Each has an optimal temperature and pH. They are affected by temperature.
