Maltose Enzyme Active Site Substrate Hydrolysed Maltase Explain

Maltase catalyzes only the breakdown of maltose because its active site possesses a specific shape, complementary to maltose, enabling the formation of an enzyme-substrate complex.

Maltase is specific to maltose breakdown because its active site's shape, determined by tertiary structure, is complementary only to maltose, allowing only maltose to bind and form an enzyme-substrate complex.

Front Maltose is hydrolysed by the enzyme maltase. Explain why maltase catalyses only this reaction. (3 marks)
Back Active site (of enzyme) has (specific) shape / tertiary structure / active site
complementary to substrate / maltose;

(Only) maltose can bind / fit;

To form enzyme substrate complex.
