There are several different types of gated channel proteins.
Name one and describe under what conditions the channel is open and
what conditions it is closed.
Describe how a signal that is relatively low in number can be
amplified within the cell. For a complete answer, you need to
include all the players and show how the signal is amplified.
4. a. we learned about 4 different types of membrane cell
receptors. describe these different types and give a spesific
example for each of them.
b. a certain patient as a mutation that nutrelizes the enzyme
that is incharge of Myristoylation of proteins. which of the types
of receptors that you descibed in question a will be affected by
this mutation? what will be the effect? what is the role of
Myristoylation? give as much details as possible.
1) Describe the types of bacterial cell arrangements and how the
different planes of cell division determine their arrangements. Why
Bacilli are less varied in arrangement than cocci? 2) Mycoplasmas
are classified as Low G + C Gram-Positive Bacteria in the textbook.
However their staining phenotype indicates they are gram negative.
What is the basis for classification as gram positive bacteria? 3)
Make a dichotomous key to distinguish among the orders of
Gammaproteobacteria
Certain single-site catalyst are capable of selectively forming
different types of polypropylene. Describe these different types of
polymer, and the characteristics of the catalysts that form
them.

a bill-and-hold arrangement would require a
manufacturer to wait and recognize revenue when the goods are
actually delivered to its customer?The manufacturer has the goods held in a separately designated
area of the plant.The customer has a substantive reason for requesting the

Describe how uranium ores can be leached in alkaline conditions.
What at the chemical reactions that occur? What are the
circumstances when you would use alkaline leaching rather than acid
leaching to recover Uranium? How will the dissolved Uranium be
recovered from the pregnant liquor solution?
