They lower the activation energy of chemical reactions. They may need a cofactor to be functional.

Factors Affecting Enzyme Activity A Level Notes Enzymes Activity Enzymes Activities

Enzymes are water soluble colloidal macromolecules which are wholly or partially proteinaceous in nature.

. They are functional proteins. C Enzymes alter the standard free energy of the reaction. All enzymes work inside cells.

Hence statement B is correct. Enzymes force reactions to proceed in only one direction Enzymes alter the equilibrium of the reaction Enzymes alter the standard free energy of the reaction All of the above None of the above. Which of the following statements about enzymes is NOT true.

Hence statement B is correct. Most enzymes are not sensitive to changes in pH. The protein part of enzyme is called apoenzyme while the non protein part is called prosthetic group which may be coenzyme or cofactor.

Hence statement A is correct. The active site has a specific shape to match the reactant s. All are not true.

View full document Which of the following is NOT true of enzymes. The substrate forms a covalent bond at the active site of the enzyme b. Which of the following statements is TRUE regarding digestive enzymes.

A Enzymes force reactions to proceed in only one direction. D All of the answers are correct. Enzyme shape may change during catalysis.

Which of the following is true of enzymes and substrates. Enzymes work best at a specified pH. All enzymes have an active site where substrates are temporarily bound d.

Enzymes are catalysts that speed up reactions. A substrate and the transition state. The active site of an enzyme orients its substrate molecules thereby promoting interaction of their reactive.

One enzyme can have many reactions. As the temperature increases from 25C to 37C enzyme activity decreases. Which of the following is NOT true about enzymes.

Each one is specific to a particular substrate to which it. Question text Which of the following isare true about enzymes. Very few enzymes require cofactors.

Enzymes are proteins that can be denatured by changes in pH or temperature. B Enzymes alter the equilibrium of the reaction. QUESTIONS Which of the following is NOT true of enzyme behavior.

Hence statement A is correct. Which of the following is true. Enzymes are specific about the substrates they can act upon d.

They function on the lock and key model. Which of the following is not true of enzymes. If the product of catalysis is present the enzyme is not acting on the substrate.

Enzymes are highly specific for the substrates they react with and catalyze only one or a limited set of possible reactions with those substrates. They are consumed by the reactions they catalyze. They are catalysts that increase the rate of a reaction.

Enzymes are water soluble colloidal macromolecules which are wholly or partially proteinaceous in nature. The protein part of enzyme is called apoenzyme while the non protein part is called prosthetic group which may be coenzyme or cofactor. The enzyme is acted upon by the substrate c.

A pancreatic proteases are normally activated in the pancreatic duct b the greatest changes in enzyme activity in the GI tract are due to pH changes c all lipases require bile starts in order to function d digestive enzymes are secreted by active transport. E None of the answers is correct. A slight change in shape can effect function.
