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

The empirical formula for biomass of an unknown organism is CH_1.8O_0.5N_0.2. To grow this organism, ethanol (C2H5OH) and ammonia are used as carbon and nitrogen

sources, respectively. Assume no product formation other than biomass. To produce 1 mol of biomass from 1 mol of ethanol, the number of moles of oxygen required will be
