Temperature
- Optimum temperature for most enzymes is 37 degrees Celsius (body temperature) {98.6 F} - Below 37 degrees they function slowly - Above 37 degrees they become misshaped and get destroyed or denatured (no longer work)
relative amounts of enzyme and substrates
-More enzyme present increases enzyme activity to a certain point and then levels off -More substrate present increases enzyme activity to a certain point and then levels off
ph level
• Scale ranging from 0-14 that measures how acidic or alkaline a substance is. • Enzymes function best at a specific pH level • Most work best at neutral pH of 7 however, some vary: Ex. Pepsin in stomach = pH 3-4 (acidic)
