What are the factors that affect enzyme activity?

• time, pressure, light intensity

• volume, color, density

• temperature, pH, substrate concentration, enzyme concentration, inhibitors or activators

• mass, velocity, energy

How is enzyme activity regulated?

• Enzyme activity is regulated through the presence of cofactors and coenzymes.

• Enzyme activity is regulated through various mechanisms such as allosteric regulation, covalent modification, and feedback inhibition.

• Enzyme activity is regulated through temperature and pH changes.

• Enzyme activity is regulated through changes in substrate concentration.
