G protein coupled and ion channel receptors
Enzyme coupled receptors
G protein coupled receptors and enzyme coupled receptors
Ion channel coupled receptors

Which complement protein interacts with Ig? Where on
the Ig protein does it bind. 5pts
Complement can lead to the formation of the MAC which
essentially lyses the target cell. Name another way
complement leads to the destruction of the target cell and the
molecules involved. 5 pts
Compare and contrast the activation steps through formation of
a C5 convertase between the Classical pathway, the Alternative
pathway and the Lectin pathway of complement
activation. 12 pts

Biotechnology of microorganisms.
You wish to synthesize an antibiotic (a protein) using a bacterium
which does not have that gene.
(a) Draw a diagram of the plasmid you would use to transform the
bacteria.
(b) How would you select the bacteria containgin the plasmid?
(c) Do you think it would be appropriate to use a species which
allow a high number of copies of the same plasmid? Why?
(d) Do you think an inducible promoter is needed to control the...
Which of the following biological functions does the protein
'myosin' perform?
Providing storage of essential nutrients
Providing strength and structure
Regulating the contraction of muscles
Transporting substance from one place to another
Protecting cells or the organism from foreign substances
Which of the following types of intermolecular/intramolecular
bonds are disrupted by the action of alkaloid reagents on
positively charged amino groups in proteins?
Dispersion forces
Disulfide linkages
Ionic bonds
Hydrogen bonds
Hydrophobic interactions
Which two molecules, an regulatory protein and enzyme regulate cell
division in mitosis?
How does the cell stop division?
What controls the breakdown of bonds between sister chromatids
so they can seperate in anaphase?
Does AUG occur only at the start of a protein? How
can a ribosome “know” which AUGs represent start codons? What is
the actual link between the amino acid and the mRNA molecule?
(IOW=What are the “translating” tools that translate RNA language
into amino acid(protein) language?hint#2=there are 64 of them)
