Master Factors Affecting Enzyme Activity fast ⚡ – clear explanations, supportive visuals, OCR-aligned.
You’ll cover
• How pH affects enzyme structure, active site shape and rate of reaction.
• How temperature influences kinetic energy, collision frequency and denaturation.
• The effect of substrate concentration on rate of reaction and Vmax.
• The effect of enzyme concentration when substrate is in excess.
• What Vmax represents and when enzymes become saturated.
• How the temperature coefficient (Q10) is calculated and interpreted.
• How serial dilutions are used to investigate enzyme-controlled reactions.
What’s included
• Clear graphs showing the effects of pH, temperature, substrate concentration and enzyme concentration on reaction rate.
• Visual explanations of denaturation versus reduced collision frequency.
• Worked examples of Vmax interpretation and limiting factors.
• Step-by-step explanation of Q10 with formula and biological context.
• Practical guidance and worked examples for serial dilution set-ups.
• Concise spec reminders embedded alongside graphs and tables to reinforce key OCR wording and expectations.
