a/ Certain molecules, such as cyanide, can bind to cytochrome c oxidase. In fact, this is the actual chemical basis of cyanide poisoning. When this happens, cytochrome c oxidase no longer works. What happens to the pH of the intermembrane space when this happens? To the production of ATP? Explain your reasoning in each case
b/ One of the reasons that freezing is bad for cells is that ice crystals can literally tear apart cell membranes. This is bad for many reasons, but why is it a problem specifically for the function of the electron transport chain?
c/ another notable feature of Antarctic icefish is that they produce what is called an anti-freeze glycoprotein. This, however, is not a unique feature of these fish, and it has in fact evolved repeatedly in many groups of eukaryotic organisms. Why would this be advantageous for icefish in particular?
