Location where substate binds

• Allosteric site

• Active site

• Coenzyme

• Cofactor

The only anion that is also an inorganic anion

• Chloride

• Magnesium

• Calcium

• Sodium

Select all that apply: Can also serve as a 2nd substrate

• Apoenzyzzme

• Cofactors

• Activators

• Coenyme

Choose the best answer: Reaction rate proportional to substrate

• Substrate concentration

Choose the best answer: Reaction rate proportional to enzzyzme

• kinetic

• First-order kinetic

• Zero-order kinetic

• Enzyme Concentration

Optimal pH of pepsin

• pH 2

• pH 7 - 8

• pH 10

• pH 5

It is a non-protein chemical compound that must bind to particular enzymes before reaction occurs.

• Coenymes

• Cofactors

• Metalloenzyzmes

• Inhibitors

Enzyzmes with the same catalytic reaction but slightly different in molecular structures

• Coenyme

• Isoenzyme

• Cofactor

• Metalloenzyme

A phenomenon where a molecule, similar to the structure of a substrate, binds to the activation site, preventing the substrate to bind.

• non-competitive inhibition

• competitive inhibition

• uncompetitive inhibition
