Play an AI-generated podcast conversation about this lesson

What is the role of cofactors in enzyme activity?

Increase enzyme activity (correct)

Cause competitive inhibition

Prevent enzyme-substrate binding

Decrease enzyme activity

What is a key characteristic of enzymes?

They do not contain an active site for substrate binding

They remain unchanged while speeding up a reaction (correct)

They increase the activation energy of reactions

They react with any substrates to catalyze biochemical reactions

How does competitive inhibition affect enzyme function?

It has no impact on enzyme activity

It fills the active site of the enzyme, competing for substrate binding (correct)

It promotes enzyme-substrate binding

It decreases the activation energy of reactions
