Enzymes lower activation energy

Enzymes lower activation energy

Induced-fit model showing substrate binding and a reaction energy profile with lower activation energy for an enzyme-catalysed reaction

Many proteins are enzymes. An enzyme is a protein catalyst that speeds up a metabolic reaction without being used up, so reactions can happen fast enough at body temperature.

Step-by-step lessons covering AQA A Level Biology Many proteins are enzymes for A Level Biology. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
