What term describes centromeres uncoupling sister chromatids separating and the two new chromosomes moving to opposite poles of the cell in miosis?

telophase
it is actually Anaphase where the sister chromatids are separated and they are pulled to opposite poles. Telephase and Cytoknesis is when the cell forms the nuclear envelope and nucleolus. The cell is then divided at the Metaphase plate and the two new daughter cells appear.

What is the significance of uncoupling proteins in adipose tissue?
increased loss of body heat
If you poke a hole in a mitochondrion can it still carry out oxidative respiration?
there will be uncoupling between oxidation of reducing equivalents and production of ATP....ie oxidation will continue to take place but NO ATP will be produced. this means that all the energy is lost as heat. this is because for ATP production a constant gradient of Hydrogen ions needs to be there....this is maintained as a result of non permeability of the inner mitochondrial membrane to hydrogen ions. when u poke a hole, it can cause leakage of H ions and the gradient is lost against whoich when H ions are pumped, its kinetic energy rotates the ATP motor( Fo particle) . hope u understood....this uncoupling takes place in brown fat. so people with brown fat can eat more but the fat doesnt get deposited. also some drugs cause uncoupling by increasing the permeability of the mitochondrial membrane this has the same affect as though creating a hole in it.
Arsenate acts as uncoupling agent for oxidative phosphorylation?
Yes. During glycolysis, arsenate which has a similar structure to phosphate replaces it from glyceraldehyde-3-phosphate to form an unstable arsenate anhydride( 1-arsenato-3-phospho-d-glycerate) that hydrolyzes to form arsenate and 3-phosphoglycerate. In the absence of phosphate, ATP is not formed in the reaction. ADP-arsenate is formed from ADP and arsenate in the presence of succinate. The formation of easily hydrolyzable ADP-arsenate complex uncouples oxidative phosphorylation and causes arsenolysis.
What are five processes or products in which either respiration or photosynthesis is controlled and used to benefit mankind?
1. In a controlled photosynthesis pond algae can be used to break down organic wastes. 2. Cultivating algae to produce biofuel. 3. Carbon dioxide mitigation through controlled photosynthesis. 4. Surgery for the treatment of gas gangrene is performed under conditions of hyperbaric oxygen because the organisms causing it are anaerobic. Antibiotics and oxygen combine to kill them more effectively than antibiotics alone because they live only in the absence of oxygen. 5. Polymixins are antibiotics that work by inhibiting bacterial respiration. 6. Other classes of drugs work by uncoupling oxidative phosphorylation in aerobic bacteria.
What is calorigenic effect of thyroid?
it produces heat by causing uncoupling oxidativephosphorylation
When you are uncoupling a loaded trailer you should lower the land gear until it Makes contact with the ground?
When the land gear is on the ground, the uncoupling can be made without the fear that the tow bar (which could be very heavy on a loaded trailer) could crash to the ground.

Why do you see stars or moving dots after you prevent yourself from sneezing out loud?
The "stars" are a result of a mechanical stimulation of the normally light-stimulated rods and cones in the retina. Rather than the light uncoupling rhodopsin to opsin and retinal, the bump uncouples them mechanically. Pressure caused by a sneeze or cough can also mechanically stimulate the photoreceptors. The final result is that "light spots" are seen.
Mitsubishi shogun 2.5 turbo diesel Black smoke lack of power then cut out now wont start?
Pulling horse box last night lacked power up hills and black smoke. On idle, kept dropping revs but kept going. After uncoupling car went fairly normal. This morning turns over but wont start.

What is receptor desensitisation?
Receptors generate a cellular response upon binding their specific ligand. This response can vary in magnitude. Desensitisation is a phenomenon in which activation of a receptor can reduce the magnitude of the response if it is subsequently activated again. Usually the longer a receptor is activated for the greater the desensitisation will be. There are 3 general mechanisms as to how desensitisation occurs. The first is uncoupling of the receptor from proteins which generate the cellular response. The second is internalising receptors so that they cannot be activated. The third is reducing production of receptors so less are available. In general mechanism 1 is short term, 2 is mid-term and 3 is long term.
What is the difference between plant cell and animal cell mitochondria?
1. Plant mitochondria have uncoupling protein that allows H+ to diffuse from the intermembrane space back to the matrix, and animals don't. Having this protein seems to decrease amount of ATP generated, so it is still unclear what its function is. 2. They also have Alternative Oxidase (AOX) which provides alternative route for electrons passing through electron transport chain to reduce Oxygen to water. 3. Two NAD(P)H dehydrogenases, both Ca2+-dependent, attached to the outer surface of the inner membrane facing the intermembrane space can oxidize cytosolic NADH and NADPH.
Is camilla wife of Prince Charles a catholic?
As is well known Catholics are not permitted to Marry divorced spouses. Charles and Diana were divorced, so in this alone, Camilla is violating ( or would be if she was a Catholic) Catholic doctrine regarding Marriage. She is of the Anglican faith. No Catholic has been King or Queen of England since the antics of Henry Viii, before Henry-of course there was only one brand of Christianity in England- Roman Catholic. Oddly , Marrying a divorced spouse , well maybe it is wrong like driving a car on a revoked license,, but this is not the same as (Pulling the Pin)- of divorce- rather like an uncoupling pin ( I am not referring to hand grenades in this context!)
What are some books one can read to learn how to cope with a divorce?
"You Can Heal Your Heart" by Louise Hay and David Kessler provides insights and strategies for healing after a breakup. "Rebuilding: When Your Relationship Ends" by Bruce Fisher and Robert Alberti outlines steps for moving forward emotionally. "Uncoupling: Turning Points in Intimate Relationships" by Diane Vaughan explores the process of breaking up and its emotional effects.
