Question

Please show the calculation

Enzymes often react with zero-order reaction kinetics. The activity of glutamate-oxaloacetate transaminase
(GOT) can be measured by coupling the production of oxaloacetate to BOT to the oxidation of NADH using
malate dehydrogenase (MDH). By monitoring the absorption value at 340 nm at 37°C we can determine the
reaction rate for this reaction.
For a zero-order reaction the following relationship can be used to determine the reaction rate:
At
= kt + Ao
Where
• Ag is the absorption at time =t
• Ao is the absorption at time = 0
k is the reaction rate
