11. Consider a squid axon bathed in seawater under artificial conditions, and the following on
concentrations: [K]i = 400 mM and [K]o = 10 mM, [Na]in = 50 mM, [Na]o = 460 mM.
Predict equilibrium potentials EK and ENa at a temperature of 13oC. Assuming that the Na permeability of the cell membrane is 1/50 that of the K permeability, predict the resting potential, Em, assuming that Cl is in equilibrium.
13 Adjacent to the neuron is a glial cell, which has no sodium channels in the plasma membrane.
Predict its resting potential, using the ion concentrations provided in Problem 11.
What organism is most probable the cause of the symptoms. What is cause the man's disease? How is this disease transmitted? How may it be prevented.
When such a drug is added, what will occur to ATP synthesis and oxygen consumption, if rates of glycolysis and the citric acid cycle stay the similar.
The sequence of the cloned DNA and the amino acids encoded by open reading frames. Stop codons are underlined and labelled 2 or 3 to indicate their reading frame.
as there is no blocking proline by either the Arg or Lys. I am stumped--what am I missing.
Explain an atom in terms of subatomic particles. Be sure to explain the size, charge, and location of each particle and how the number of each of those particles affects the atom.
Think of the beaver's digestive organ system. Clarify its overall role. List several of the organs in this system, describe how each functions, and outline how organs work together to carry out the role of the organ system.
Explain how tail length is inherited. Indicate how many gene pairs are at work and designate the genotypes of the two parents and lf the F1 offspring.
How can altering ice nucleation protein production yield a bacterial strain useful to agriculture? Explain the logic and how this works.
A two electron transfer reaction you are studying has a standard state standard reduction potential (Eo') on 0.137V at 37C. What is the equilibrium constant for the reaction (Keq') at 37C.
What is the difference between theory and hypothesis and explain the importance for a hypothesis to be testable and falsifiable in order for the scientific method to be applied
Choose one biotechnology example, such as agriculture, medical or historical, and provide at least two ways use of this biotechnology could benefit society and two ways this biotechnology could be harmful.
make an experiment to test what happens (i.e. what is the final plasmid DNA content of cells in a transformed colony) if a competent cell is transformed with circular double-stranded plasmid DNA where there is a mis-match (e.g. a G-T base-pair ins..
