Enzyme Thermodynamics (Binding Energy and Entropy)

The video tutorial discusses binding energy in enzyme reactions, focusing on entropy reduction, desolvation, and induced fit. It explains how magnesium stabilizes ATP in hexokinase, leading to a decrease in entropy. The desolvation process increases entropy by expelling water from the active site. Induced fit involves conformational changes in enzymes, bringing catalytic residues closer to substrates, facilitating reactions.
