What does an enzyme- substrate complex form when a substrate binds to an enzyme's active site?


What is the compound on which an enzyme acts?


Where does catalysis occur in an enzyme?

Active site

What is the energy barrier that substrates need to overcome before a reaction occurs?

Activation energy

What do enzymes lower in order to allow substrates to react faster?

Activation energy

Which of the following is true about cofactors?

They can be both metals and small organic molecules.

What is the function of prosthetic groups?

Bind transiently to the enzyme or substrate.

Which of the following is an example of a metal cofactor?

Manganese (Mn)

What is the main difference between absolute specificity and group specificity?

Absolute specificity only acts on one reaction, while group specificity acts on specific functional groups.

According to the lock-and-key model of enzyme binding, what is the nature of the active site?

It is rigid in shape and complementary to the substrate.

Test your knowledge on enzymes, the proteinic molecules that act as catalysts to speed up biological reactions, including their structure, function, and specificity.
