Rate of reaction increases proportional to increase in [substrate]Rate of reaction then levels off/ plateaus not all active sites are being used; adding substrate increases RoR all active sites used/ [enz...

At optimum pH, active site is complimentary to substratepH changes disrupt H-bonds/ ionic bonds

1. Increasing temperature increases KE of molecules1. so more enzyme-substrate (E-S) collisions1. more E-S complexes formed2. Hydrogen/ ionic bonds broken2. Enzyme becomes denatured2. Active site chang...

Taken from AQA specification learning outcome 4.1.1.2Students should be able to explain how the main sub-cellular structures, including the nucleus, cell membranes, mitochondria, chloroplasts in plant cel...

Meiosis is formed of meiosis I and meiosis II. You start with a diploid cell (2n). The DNA is replicated in this diploid cell and recombination occurs, where the two chromosomes may swap over bits of DNA....
