Enzymes alter the equilibrium distribution of the substrate s and product s of the reaction they catalyze.

. Enzymes employ a wide variety of catalytic strategies. Which of the following properties is NOT a characteristic of enzymes A Enzymes from BCHS 3304 at University of Houston. 5 Which substances are commonly used as the building blocks in the.

Enzymes vary widely in their catalytic efficiencies. Choose all that apply Allosteric enzymes. They are proteins B.

Each has a specific substrate. S C generally have more than one subunit D conform to Michaelis-Menten kinetics. Sticky end restriction enzymes leave overhanging nucleotides in dsDNA that they have cut c.

Which of the following is not a characteristic of the immobilized enzymes. - A They cannot be re-used - B It produces reproducible results. Each has an active site.

C They lower the amount of energy present in the substrate. CAn enzyme is unchanged as a result of a reaction. Sticky end restriction enzymes are useful for cloning unknown sequences of DNA.

The study of the bodys proteins is known as proteomics. AThe substrate is the substance upon which the enzyme acts. Which of the following is not a characteristic of enzymes.

Enzymes are usually named by adding the suffix -ase to the name of its substrate. Enzyme catalysis is dependent on the pH and temperature of the reaction environment. The synthesis of a protein by following the genetic code is known as gene expression.

They are required in minute amounts. They are affected by temperature. Enzymes alters the speed of a chemical reaction.

Protein synthesis requires messenger RNA and transfer RNA. Which of the following is not characteristic of an enzyme. The amount of energy required to raise the energy of molecule at which chemical reaction can occur is called activation energy.

Which of the following is not a characteristic of enzymes. Which of the following is characteristic of enzymes. A They lower the energy of activation of a reaction by binding the substrate.

An enzyme is specific as the reaction it will catalyze. Sticky end restriction enzymes allow for very selective insertion of a gene of interest into a bacterial. They act on specific substances called substrates.

Which of the following are characteristics of allosteric enzymes. A may have binding sites for regulatory molecules that are separate from active sites B tend to have a hyperbolic curve of v₀ vs. B They raise the energy of activation of a reaction by binding the substrate.

F they are proteins G they act as a catalyst H they react with a specific substrate they are unaffected by changes in temperature J they are unaffected by changes in temperature. Enzymes provide activation energy for the reaction they catalyze. Enzyme catalysis is dependent on the three-dimensional structure or conformation of the enzyme.

Characteristics of an Enzyme. 3 Which substances are most commonly used as building blocks in the synthesis formation of lipids. Each is used to break down substances.

The above reaction it is clear that enzymes can initiate and decelerate chemical reactions. They speed up the rate of chemical reactions C. Ace your General Science and Biology preparations for Cell with us and master Biomolecules for your exams.

Which of the following is NOT a characteristic of restriction enzymes that leave sticky ends. They are chemically proteinaceous in nature. They are highly specific in their action.

2 Which structural formulas represent carbohydrate molecules. They work best at optimum temperature. Most of the bodys proteins have been studied thoroughly.

Enzyme E reacts with substances S to form a product ES. When reactions proceed from one direction to another enzymes have to overcome an energy barrier to activate the inactive molecule. D They react chemically with the substrate and gradually get used up in the process.

Most of the bodys thousands of proteins have been studied thoroughly. Each has an optimal temperature and pH. Main characteristics of enzymes.

Enzyme is biomolecule that catalyzes the chemical reaction. Enzymes reduce the activation energy of the reaction they catalyze. Which of the following is not a characteristic of enzymes.

Enzymes are composed primarily of protein but they may bind nonprotein cofactors. 4 What are the different types of biomolecule describe each structure. BThe induced-fit or lock and key model describes how enzymes work.
