Question

1 multiple choice 10 points which statement about enzymes is false? enzymes lower the activation energy needed to initiate chemical reactions. some enzymes require coenzymes (which are carbon - containing molecules) to function. some enzymes require cofactors (which are inorganic ions) to function. an enzyme is permanently altered after speeding up a reaction. at low substrate concentration, the presence of an enzyme greatly increases the rate of a reaction, but once the enzyme becomes saturated, the reaction rate levels off. clear my selection

Explanation:

Enzymes are biological catalysts. They lower activation - energy for reactions. Some need coenzymes (organic) or cofactors (inorganic) to function. At low substrate levels, they increase reaction rate and the rate levels off at saturation. Enzymes are not permanently altered after a reaction; they can be reused.

Answer:

An enzyme is permanently altered after speeding up a reaction.
