Question

Five graduate students prepare extracts from 5 different tissues. Each student measures the total amount of alcohol dehydrogenase and the total amount of protein in his or her extract. Which extract has the highest specific activity?

extract Total protein(mg) Total alcohol dehydrogenase activity (units)
A 300 60,000
B 200 80,000
C 3,000 90,000
D 5,000 100,000
E 1,000 200,000

Answer 1

B

Step-by-step explanation:

If you convert all the options to standard form and compare the relative exponents and values, one can now decide which one is the highest.

A quick comparison shows that option B. This value thus represents the highest activity among the options listed in the question. Hence the answer provided above.
