Question
Chapter 5, Problem 30E
Summary Introduction
To analyze:
The fate of the cells that normally secrete epinephrine, but a defect occurred in the enzyme Phenylethanolamine N-methyl transferase (PNMT).
Introduction:
Phenylethanolamine N-methyl transferase (PNMT) is an enzyme that catalyzes the production of epinephrine and is present in the cytosol. Any defects that occur in the enzyme Phenylethanolamine N-methyl transferase (PNMT) causes a lack of production of epinephrine from norepinephrine.

- engineered constructs that consist of hollow fibers are acting as synthetic capillaries, around which cells have been loaded. The cellular space around a single fiber can be modeled as if it were a Krogh tissue cylinder. Each fiber has an outside “capillary” radius of 100 µm and the “tissue” radius can be taken as 200 µm. The following values apply to the device:R0 = 20 µM/secaO2 = 1.35 µM/mmHgDO2,T = 1.67 x 10-5 cm2/secPO2,m = 4 x 10-3 cm/secInstead of blood inside the fibers, the oxygen transport and tissue consumption are being investigated by usingan aqueous solution saturated with pure oxygen. As a result, there is no mass transfer resistance in the synthetic“capillary”, only that due to the membrane itself. Rather than accounting for pO2 variations along the length ofthe fiber, use an average value in the “capillary” of 130 mmHg.Is the tissue fully oxygenated?arrow_forwardMolecular Biology Please help with question. thank you You are studying the expression of the lac operon.
