October 3, 2005 enzymes Structure: Globular protein that fold into complex 3D structures called confirmations Function: Regulate cellular functions by binding to substrate on its active site. They also reduce activation energies. E + S ES EP E + P E = enzyme S = substrate P = product What enzymes do… Orentation maintain a correct orientation. Substrate stabilizes transitional state by alterind the electron distribution of the substrate. Causes physical stress on the chemical bonds that need to be broken, lowering activation energy. Every enzyme has an optimal pH, temperature.
