Question

1) A) Embryonic liver tissue contains an enzyme that catalyzes the reaction SP activity. Some kinetic data are shown below. What conclusions can you draw concerning the identity of the two enzymes?

[S]                               Observed Initial velocity (moles/mg protein/min

(M)                  Extract of Adult Liver (E1)    Extract of Embryonic Liver (E2)

1.67 X 10-5                    1.05                                         5.00

2.5 X 10-5                    1.54                                         6.66

3.33 X 10-5                  1.98                                         8.00

5.0 X 10-5                    2.86                                         10.00

7.0 X 10-5                    3.78                                         11.67

1.0 X 10-4                    5.00                                         13.33

1.5 X 10-4                    6.67                                         15.0

1.67 X 10-4                  7.15                                         15.4

2.0 X 10-4                    8.00                                         16.0

3.0 X 10-4                    10.0                                         17.1

Explanation / Answer

The conclusion that can be drawn from the data is that the turnover of enzyme present in embryonic liver (E2) extract is more when compared to the enzyme present in the adult liver extract (E1).

Embryonic liver the reaction takes place faster because the growth is also at a faster pace
