Trade secret protection can be an effective strategy in an environment where patent protection is weak, and it has the additional advantage of being consistently less expensive than patenting in both the short and long term.

Problem 1: 40 points

You are trying to conduct an in vitro experiment on a 3-D tissue construct in the lab. The construct is a rectangular slab (3 cm x 5 cm x 0.25 cm) and cells occupy 65% of the total volume. You wish to ensure that sufficient oxygen is provided to the cell culture media to support the tissue growth. Unfortunately, You are not able to directly measure the oxygen consumption rate in the cells. Thankfully, you realize that the cell type for your experiment is well studied in vivo. After some literature searching you are able to find the following information reported for your cell/tissue type: 1) the partial pressure of oxygen in the specific supply artery and exit vein to/from the tissue are measured to be 92mmHg and 22mmHg

 

A. Based on these reported measurements, what is the fractional saturation of oxygen in each blood vessel? (10 points)

 

 

B. Using the literature values for the in vivo measurements, determine the oxygen consumption rate of the cells in mole (min mL tissue) $)^{-1}$. (10 points)
