#Section 5: Bioprocess Engineering and Process Biotechnology
Enzyme activity was monitored over the last two stages of an enzyme extraction-separation process. 0.4 g protein, from Stage 5, converted 46 mmol substrate in 10 sec, and 0.02 g protein, from Stage 6, converted 49 mmol in 30 sec. Calculate the specific activities in units/g at each of the two steps
