Enzyme activity vs temperature
Webmeasuring enzyme activity is normally to determine the amount of enzyme present under defined conditions, so that activity can be compared between one sample and another, and between one laboratory and another. The conditions chosen are usually at the optimum pH, ‘saturating’substrateconcentrations,andatatemperature WebDec 30, 2024 · The temperature optimum of most enzymes is very close to its typical environment. Thus, a human enzyme would operate optimally around 37°C, while an enzyme from bacteria that live in deep-sea volcanic vents (e.g. Thermophilus aquaticus) might have temperature optima over 90°C. This is one of the reasons that refrigeration …
