Document Summary

Proteins are a complex molecule with structures that are diverse and have diverse functions. For a protein with a single polypeptide chain, a small protein would be about 5 to 10 kda, a medium protein would be 20 kda and a large protein on the order of 50 kda. If we understand how proteins work, and what s not working properly in diseased states, we may be able to design pharmaceuticals that correct the abnormalities associated with human disease. Lipoproteins in blood carry lipids from the liver to tissues. Proteins are the molecule machines that make life possible. If we are to understand life, we must understand protein function. And when proteins have mutations, this lead sot human disease. Proteins are the targets of most pharmaceutical products. Catalyze the millions of chemical reactions that occur in cells. Ex. luciferase enzyme in fireflies which catalyzes the oxidation of luciferin, releasing green light.

Proteins perform many roles in cells. Which of the following in a role you would NOT expect for proteins?

a. Proteins can carry out enzymatic reactions.

b. Proteins can bind to DNA to regulate translation.

c. Proteins can transport chemical species across the cell membrane.

d. Proteins can transport molecules like oxygen through the blood stream.

1)
Proteins are more the most functionally diverse macromolecules , other than enzymes ,what are two functions of protein ?give general examples of each protein.

2)
What are the what is the difference between passive transport and active transport? give at least one example of each.

2. Cellular transport of proteins is very important in order for a cell to function properly. For each of the mutations below, (1) explain what type of transport will be affected by explaining the correct transport process and where the problem will arise and (2) where the proteins that are transported incorrectly will be found (8 pts). (1) A mutation in N-acetyl transferase, the enzyme that adds N-linked glycosylation to proteins. (2) A mutation in the TIM22 complex. (3) A mutation that causes GTP to not be hydrolyzed in the cytosol (4) A mutation in the signaling molecule that causes the regulated secretion of insulin (a protein hormone)
