The
answer is ‘they create tension by pulling toward opposite poles’. Kinetochores change
between persistent phases of movement towards the pole (poleward) or inversed
(anti-poleward), which are coupled with alternating states of kMTs (kinetochore
microtubules) depolymerization and polymerization, respectively. A low tension
at kinetochores promotes change towards kMTs depolymerization, and high tension
promotes change towards kMTs polymerization.
Parasite: Parasites are different from predators because parasites only take resources from one host, whereas predators eat many prey. A good example of this is the trematode parasite Schistosoma mansoni. An adult schistosome parasite lives inside of just one human host
Answer:
1. The reason there is energy released in the process is because the products formed (ADP and hydrogenphosphate/phosphate) have stronger covalent bonds (plus intermolecular forces with the surrounding solution and dissolved ions) than the starting materials.
2. The end product of oxidative phosphorylation is ATP and water. ATP synthesis is coupled with the transfer of electrons to O2, which combines with protons to form water. Phosphorylation is the chemical addition of a phosphoryl group (PO3-) to an organic molecule. The removal of a phosphoryl group is called dephosphorylation. Both phosphorylation and dephosphorylation are carried out by enzymes (there are enzymes involved). kinases and phosphatases, From the family of Enzymes.
You are supposed to go take a walk and observe your surroundings. The concepts taught in your class are to be used so if you give me what you learned that would help. So out of those 10 relationships of each biological surrounding you list the concept taking place and then pick 5 and write a summary on the back of the page. Hope this helps...
