Perhaps it would be good to create a checklist of things to write in your essay, similar to the PEEL format for GCSE students or something slightly more complex for older students. It is important to memo...

2^x = e^{ln(2^x)} = e^xln(2) , d/dx(e^xln(2)) = ln(2)e^xln(2) = ln(2)*2^x

let u=kx,du/dx=ky= 4 sin(u)dy/du= 4cos(u)
dy/dx= du/dx*dy/du = 4kcos(u) =4kcos(kx)

When an enzyme comes into contact with a substrate that fits its active site, it will bind to it and form an enzyme-substrate complex. This binding alters some of the bonds in the substrate to be slightly...
