The zinc most likely functions as an A competitive inhibitor of the enzyme.

. Enzymes function best at an optimum temperature 20-40C. According to the most widely accepted theory enzymes bind to the substrate molecule and form a transition state. Enzymes affect the rate of a reaction by lowering the energy needed to initiate the reaction.

Correct option is A Enzymes are biological catalysts which speed up biochemical reactions. Hence statement D is correct. Enzymes increase the rate of chemical reaction the enzymes accelerate the chemical reactions but do not change the value of equilibrium constant of the reaction.

Enzyme function is influenced by physical and chemical environmental factors such as pHand temperature. This type of inhibition is known as A allosteric inhibition. Enzymes increase the rate of chemical reactions by increasing activation energy barriers.

B noncompetitive inhibitor of the enzyme. A energy released when chemical bonds are broken. Unlike potential energy Ainetic energy can be referred to as.

Enzyme function is reduced if the three-dimensional structure or conformation of an enzyme is altered. How does a noncompetitive inhibitor decrease the. Which of the following is not true concerning enzyme activity.

Answered expert verified Which of the following is true regarding the structure of enzymes. During the progress of a reaction the substrates are separated from products by an energy barrier which the substrates need to cross. A substrate molecule bound to an active site affects the active site of several subunits.

Enzymes are not altered in the course of their action. The shape of enzymes change to fit all types of substrates. The enzyme activity decreases with slight decrease or increase from the optimum temperature range.

Most enzymes work with a wide variety of substrates. Enzymes form temporary compounds with their substrates. The arrows represent reactions catalyzed by the indicated enzyme.

The correct answer to this question is A Enzymes lower the activation energy and the ΔG produced from a reaction. D answers a c. At very high temperature enzyme activity decreases because denaturation of proteins occurs and enzyme becomes inactive.

See full answer below. Transferases are enzymes that catalyze the transfer of groups such as amino and phosphate groups between compounds. C energy of atomic molecular motion.

An enzyme gretly reduces the activation energy E A. Enzyme function is generally increased if the three- dimensional structure or conformation of an enzyme is altered. The letters represent chemical compounds consumed or produced during the reactions.

Which of the following would be true of the enzymeSelect all that apply Athe active site of the enzyme must be rigid Bthe active site of the enzyme must be flexible Conly one substrate could be converted to product by the enzyme Dthe enzyme could bind different substrates if the substrates shared a common motif somewhere in their structures Ethe entire enzyme must be. E answers a b c. The active site is where the enzyme binds with the substrate.

Enzymes are considered organic catalysts. B energy that is stored in bonds. C allosteric activator of the enzyme.

All of the above are true of enzymes. The International Comission of Enzymes of the International Union of Biochemistry has categorized all enzymes into one of these classes. Necessary to initiate a chemical reaction.

Enzymes increase the rate of chemical reactions by providing activation energy to the substrate. 27 All of the following are true concerning enzymes except that theydocx. Enzymes act as catalyzing.

D Enzymes are denatured once they are used in a chemical reaction. Sulfanilamide is an antimicrobial drug that mimics the shape of an important substrate for a particular bacterial enzyme thereby inhibiting the enzyme. If the action of enzyme 1 is blocked with an inhibitor all of the following statements is true about the effect on the pathway except.

Enzymes increase the rate of chemical reaction by lowering activation energy barriers. Zinc an essential trace element for most organisms is present in the active site of the enzyme carboxypeptidase. Oxidoreductases transferases hydrolases lyases isomerases and ligases.
