You are assessing the activity of an enzyme using spectrophotometry. The absorbance measured at 340 nm increased from 0.200 to 0.250 over 5 minutes. Calculate the initial reaction rate (V0).
💡 Hint: Remember to focus on the relationship between absorbance change and time.
In a titration experiment designed to assess enzyme activity affecting pH, you observed that the pH dropped from 7.4 to 6.5 after enzyme addition. Convert this change into moles of acid produced if the buffer capacity is known to be 0.1 M.
💡 Hint: Consider how pH change correlates with acid concentration.
