Which of the following are correct regarding enzymes? Select all that apply. Enzymes require stable environmental conditions. Enzymes can work across a wide range of environmental conditions. Changes in pH or temperature do not cause changes in protein shape Changes in pH or temperature can cause changes in protein shape enzyme shape change, changes enzyme function Enzymes are catalysts. Enzymes can make reactions happen that would never occur without them Enzymes speed up reactions, but cannot make a reaction happen that would not normally occur

Which of the following statements about enzymes is true? Select one: a. Enzymes increase the rate of a chemical reaction by raising the activation energy for the reaction b. Enzymes react with their substrate (form chemical bonds), forming an enzyme-substrate complex, which irreversibly changes the enzyme c. Enzymes work equally well at any temperature d. Enzymes can typically bind many types of substrates e. None of the above

Which of the following statements about enzymes are true? Select all that apply: Enzymes increase reaction rates by lowering the energy of the products. Enzymes increase the rate at which products are created by preventing reactions from running backwards. Enzymes increase reaction rates by lowering the activation energy of a reaction. Enzymes increase reaction rates by interacting with the substrate molecules to facilitate the reaction, for example by contorting them to facilitate bond-breakage or orienting them to favor bond formation.
