Optimum pH for enzymes in the human body is 6. It's a bell shaped Graph. At Higher or lower pH, the alkalinity/acidity denatures the enzyme, which changes the shape of the active site, and so the substr...

Chain Rule: dy/dx = dy/du x du/dxy=e^3-2xSubstitute u for the power (3-2x) y = e^u u = 3-2xdy/du = e^u du/dx = -2dy/dx = -2e^u = -2e^3-2x

All living things need food to survive. However, plants cannot nip down to tesco to buy themselves a pizza, instead they make their own food. This process is called photosynthesis. Plants take in carbon d...
