Explain why do you think the plasma membrane exists in all living things? Why aren't there living things that do not encompass a membrane at their periphery?
1) Explain why must particles be extremely small to explain Brownian movement? 2) Describe the difference between molecular motion and diffusion?
Describe why phospholipids encompass a natural tendency to self assemble into a bi-layer. Explain why is this biologically significant?
I want a basic explanation of the difference in the rates at which glucose is transported across the cell membrane versus the concentration gradient of glucose.
Describe how the axonal membrane potential is restored following action potential depolarization. Explain h how resting ionic distributions are maintained.
What sorts of member molecules might be distributed asymmetrically? Explain why does it make sense for some components of membranes to be asymmetrically distributed?
1) Describe why the coupling of the import of amino acids or sugars into cells is usually linked to Na+ ion import. 2) What happens to the post-synaptic cell's membrane potential at an inhibitory syna
As materials move from high concentration to the low concentration by simple diffusion, and they move the similar way by facilitated diffusion, explain why do cells make proteins to carry out facili
How are proteins targeted to various compartments with in a eukaryotic cell? Please give a detailed illustration of how a protein is targeted to the specific organelle.
Explain how does an integral membrane glycoprotein travel from ER to the Golgi and from the Golgi to the plasma membrane? Describe the modification which goes on to this protein?
The addition of oligomycin to mitochondria markedly reduced both the rate of electron transfer from NADH to oxygen and the rate of ATP formation.
Nigericin is an ionosphere which exchanges K+ for H+ across membranes. Describe how the treatment of functioning mitochondria with nigericin uncouples electron transport form oxidative phosphorylati
Several chemicals block ATP synthesis by permitting protons and other ions to "leak across membranes," disrupting the charge and protein gradients established by the electron flow via an electron tr
Is the production of water by the electron transport chain catalyzed by the cytochrome oxidase, ubiquinone, cytochrome c, cytochrome b or complex I?
Compare and contrast the divisions of the autonomic nervous system's effect on the heart rate and stroke volume.
Please give some information regarding the relationships between the intra-cellular compartments included in the secretory and endocytic pathways, as well please differentiate between co-translation
In several countries, human waste is employed as a fertilizer. If produce is grown in this kind of fertilizer, it is possible that it will be contaminated with the protozoan which causes amoebic dys
What will occur to the volume of the cells as a consequence? Explain why is proper hydration significant for multi-cellular organisms?
Start by distinguishing between the osmosis and diffusion; how are they alike? In what manners are they different?
A perfume company wishes to dispense 13.9 quarts of a new fragrance into the small vials. Determine how many 25 ml vials can they fill?
The major difficulty in investigating the properties of pancreatic serine proteases is that these enzymes, being proteins, are self digesting. The problem is less rigorous for solutions of chymotry
How many different possible disaccharides can be made between the pyranose forms of D-galactose and D-glucose? Explain how many are non-reducing?
Describe the feasibility of using methylation analysis to differentiate between each of the given pairs of carbohydrates: A) Maltose and Trehalose B) Maltose and Amylose C) Amylose and Cellulose
In order to find out the main pathway of glycine degradation, you devise an experiment in which mice are fed 13C (alpha)-labeled glycine, and the livers are then isolated and radioactive intermediat
Estimate the amount of energy a mammal can get from the oxidation of palmitate, in the liver beneath conditions of ketosis, relative to the amount obtainable under conditions of a balanced diet with
