Eukaryotic cells are complex in organization and structure, especially when you consider their small size. Consider the organelle contents of the typical eukaryotic cell.
House the neurtransmitters that will ultimately be released into the synaptic cleft in response to an action potential arriving at the nerve terminal.
A standard procedure in pufying tubulin is to extract the tissue on ice, then add GTP and warm the tissue extract to 37C. The warmed extract is then centrifuged at a speed insufficient to pellet ave
Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat.
What sorts of member molecules may be distributed asymmetrically? Why does it make sense for certain components of membranes to be asymmetrically distributed? Give specific examples. How can a membr
Explain what pumps and/or transporters are involved in moving neurotransmitters into synaptic vesicles.
Give a functional definition of a eukaryotic gene. Please include all parts of a eukaryotic gene and what the function of each element is. Which parts of a newly synthesized eukaryotic mRNA molecule
The addition of oligomycin to mitochrondria markedly drecreased both the rate of electron transfer from NADH to oxygen and the rate of ATP formation.
Nigericin is an ionophore that exchanges K+ for H+ across membranes. Explain how the treatment of functioning mitochondria with nigericin uncouples electron transport form oxidative phosphorylation.
Certain chemicals block ATP synthesis by allowing protons and other ions to "leak across membranes," disrupting the charge and protein gradients established by electron flow through an electron tran
Compare the divisions of the autonomic nervous system's effect on heart rate and stroke volume.
Several ions are responsible for the resting membrane potential. Describe the forces that determine resting membrane potential.
You were cleaning out the aquariums in the biology lab and you accidentally placed the saltwater fish in the freshwater tank. What will happen to the cells of these fish.
Synaptic vesicles are released at the synaptic cleft in response to action potentials arriving at the nerve terminal.
All cells are surrounded by a phospholipid bilayer membrane. The function of the phospholipid bilayer is to act as a barrier between the living cell and the environment.
The integrity of the plasma membrane is essential for cellular survival. Could the immune system utilize this fact to destroy foreign cells that have invaded the body? How might cells of the immune
All life forms on Earth exist either as single cells or as collections of cells that have a plasma membrane at their periphery (though some cells have cell walls outside their plasma membrane). Why
Mary noticed a large, brown spot on her skin. She has been playing tennis in the sun for several years without sun protection. She reported the discovery to a friend.
If you immerse your hand in distilled water for 15 minutes, will you cells lyse? why or why not.
Are your conclusion about membrane structure and stress valid only for beet cells? Why or why not.
Answer the multiple choice questions. Explain the reason.
If you were trying to determine the function of your favorite nucleoporins, your first experiment would be to see whether it binds to other nucleoporins. What type of experiment would you perform? W
In mice, there are viruses that are known to cause cancer. You have a pure preparation of virus DNA, a pure preparation of DNA from the chromosomes of mouse cancer cells.
Avery, MacLeod, and McCarty who repeated the transformation experiments of Griffith, and chemically characterized the transforming principle.
