pH Biology · Enzymes & Digestion Mastery Workbook

Enzymes are one of the most testable topics on the Higher Biology paper — and the rules are surprisingly clean once they click. This 25-page Mastery Workbook drills the lock and key model, the factors that change enzyme activity, the full digestive system and every food test on the syllabus.

What's inside

·       65 exam-style questions across enzymes, factors, digestion, food tests and the required practical.

·       The amylase pH required practical set up step by step, with controls and one common source of error.

·       All four food tests — iodine, Benedict's, Biuret and the emulsion test — explained with positive and negative results.

·       Worked solutions for every question with “common slip” notes flagging the mistakes examiners punish.

·       Topic overview plus 10 exam-style questions in the style of real Higher papers.
