You are a drug designer. You have developed a drug that needs to work inside cells. What challenges confront you? How do you circumvent those challenges?
Give an example of passive transport. What is the difference between this and active transport?
Homework Answers
*First of all, we have to know that whether it is transport into the cell or not. This can be find out by means of GFP protein. We will insert some GFP protein with these drug. If it will move inside, then Fluorescence also found inside the cell.
* We have to know the effect of these drug in the cell. For this, we have to take control experiment in which there is no use of drugs and ins Second experiment, we use drug. Now compare the physiology of two cell.

Example of passive transport:
Diffusion in which molecules are move from high concentration to low concentration without use of energy.
Difference between active and passive transport:
| Passive transport | active transport |
| There is no utilisation of energy | Energy in the form of ATP is needed. |
| It occurs along the concentration gradient | it occurs against the concentration gradient |
| Example: osmosis, diffusion | example: endocytosis, exocytosis. |

An experimental drug is being developed to selectively inhibit TH cells to prevent organ rejection. How will this help patients? When TH cells are inhibited, macrophages become less phagocytic and will not attack the donated organ. By inhibiting TH cells, B cells will be able to proliferate extensively, allowing them to protect the donated organ from rejection. Inhibiting TH cells will reduce the number of phagocytic TH cells in the blood which in turn will do less damage on the...

You work for a pharmaceutical company that has developed a new
drug. The patent on the drug will last 17 years. You expect the
drug’s profit to be $4 million in its first year and this amount
will grow at a rate of 3% per year for the next 17 years. Once the
patent expires, other pharmaceutical companies will be able to
produce the same drug and competition will drive profits to zero.

Part A: Suppose you work for a pharmaceutical company that is testing a new drug to treat ulcerative colitis. You conduct a random sample of 34 patients on the new drug and 14 of them indicated a decrease in symptoms since starting the drug regimen. You construct a 90% confidence interval for this proportion to be ( 0.2733 , 0.5502 ). What is the correct interpretation of this confidence interval? 1) We are certain that 90% of patients will be...

You work for a pharmaceutical company that has developed a new drug. The patent on the drug will last 17years. You expect that the drug's profits will be $1 million in its first year and that this amount will grow at a rate of5% per year for the next 17 years. Once the patent expires, other pharmaceutical companies will be able to produce the same drug and competition will likely drive profits to zero. What is the present value of...

You are a scientist working for a lab attempting to develop an anti-obesity drug called glucono. The idea is that glucono could be added to the diet to reduce glucose and calorie absorption; even though glucono would be absorbed, it would not be metabolized, and would be excreted by the kidney. The hypothesis is that glucono binds to the Na+/glucose transporter that is a part of secondary active transport of glucose. This cannot be easily studied in humans, so you...
