Enzymes regulate metabolic pathways
Enzymes regulate metabolic pathways
Metabolism is the sum of all chemical reactions in an organism, and enzymes are globular protein catalysts that speed these reactions up without being used up. Because each enzyme only catalyses particular reactions, cells can control metabolism by controlling enzyme activity or availability.
Step-by-step lessons covering Eduqas A Level Biology Biological reactions are regulated by enzymes for A Level Biology. Each lesson works through exam-style questions in Component 1, Component 2 and Component 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.
