Learn about the proteins that can help enzymes catalyze reactions known as cofactors and coenzymes. [9:59]

A video exploring how to use Gibbs free energy to figure out if a reaction is going to be spontaneous or not which is helpful in biology. [9:18]

This lesson will describe how an enzyme is used to turn substrate into product. It is 1 of 5 in the series titled "Enzyme Function."

This lesson will describe that enzymes are made of proteins, and can be found in nature or can be synthesized synthetically. It is 1 of 4 in the series titled "Enzyme Structure."

This lesson will describe the process of induced fit, and explain how enzymes use it during chemical reactions. It is 3 of 3 in the series titled "Induced Fit."

This lesson will show that each enzyme fits to a specific structure using the lock and key model. It is 1 of 4 in the series titled "Lock and Key Model."

This lesson shows that an active site is the space on an enzyme where a substrate would attach. It is 2 of 4 in the series titled "Active Site."

This lesson shows that an active site is the space on an enzyme where a substrate would attach. It is 1 of 4 in the series titled "Active Site."

This lesson will describe that a catalyst is something which can speed up a reaction by lowering activation energy. It is 3 of 4 in the series titled "Catalyst."

This lesson will introduce the two types of inhibition found in enzyme interactions: Competitive Inhibition and Noncompetitive Inhibition. It is 3 of 4 in the series titled "Competitive and Noncompetitive Inhibition."

This lesson will describe how an enzyme is used to turn substrate into product. It is 5 of 5 in the series titled "Enzyme Function."
