24 Questions
What is the result of the complementary nature between the shape of the active site on the enzyme and its substrate(s)?
The specificity of an enzyme is achieved
Why do enzymes have specific three-dimensional shapes?
Because they are formed from protein molecules
What determines the shape of an enzyme?
The order of amino acids
What is the 'lock and key theory' used to explain?
Enzyme action
What happens when an enzyme and its complementary substrate collide?
An enzyme-substrate complex forms, and the reaction occurs
What forms from the substrate(s) during an enzyme-substrate reaction?
A product (or products)
What is the role of the active site of an enzyme?
To bind to a specific substrate
What is the function of an enzyme in a living organism?
To catalyse specific chemical reactions
What is the primary role of enzymes in biological reactions?
