The toolbox of philosophy is argumentative logic and that of science is the scientific method. Philosophy dwells on questions that science (at least at the present) cannot answer philosophy though does not give us unequivocal answers but a list of possible equivocal answers, deduced and induced by l...

question regarding the Bohr effect and Haldane effect

according to the haldane effect ( "Principles of Animal Physiology" Chistopher D. Moyes) "Oxygenated hemoglobin releases bound H+ ions...and shifts the CO_2 -bicarbonate reaction to the left, reducing the amound of HCO_3- in the blood, and reducing the amount of CO_2 that can be carri...

Bohr effect and Root effect

Could someone explain the particular differences between the two? What I do know (or think I know) Is that both are due to a decrease in PH by carbonic acid found produced in the tissues. H+ ions bind to hemoglobin which either decreases its affinity for O2 (the Bohr effect) or it decreased the O2 c...

So when the cytoplasm is in the form of cytogel the actin arrangement is some what conpact holding it together in a gel-like form, and when the actin filimants extend they become somewhat less conpact allowing its transformation into cytosol ?

Actin filiments role in ameoboid movement

I know that during amoeboid movement the cytogel of the ectoplasm is converted to cytosol and is forced to the cells perifery at a localized area forming a hylane cap which than extends into a pseudopod. I also know that actin filimanst of the cytoskelceton play a role in converting cytosol into cyt...

I do know that the former uses Co2 and the latter uses other carbon based compounds but this difference seems mundane to me a...
