Question

1. which of the following statements is true about enzymes and substrates? each enzyme has many sites to fit all substrates. each enzyme can form many products from a specific set of substrates. each enzyme has specialized sites that only fit certain substrates. each enzyme is designed to work with substrates from all metabolic reactions.

Explanation:

Enzymes exhibit specificity, meaning their active sites (specialized binding sites) only match and bind to particular substrates, based on the lock-and-key or induced fit models of enzyme-substrate interaction. The other options are incorrect: enzymes do not fit all substrates, do not produce many products from a specific substrate set, and do not work with all metabolic reaction substrates.

Answer:

Each enzyme has specialized sites that only fit certain substrates.
