well aconitase converts citrate to isocitrate via cis-aconitate intermediate, don't know if that helps you.

ATP is basically the goal of catabolism, but there's not point continuing breakdown if you've got enough ATP for whatever you're doing, better use your time on other things. simply put.

look up the cori cycle. Lactate is recycled to the liver where it can be used in gluconeogenesis to regenerate glucose...

think about what a sequence alignment is... in terms of looking for ORF's, you would probably use a tool like Expasy for that, sequence alignments serve a different purpose. Assuming line 1 and 3 are continuous, as are 2 and 4, what do they tell you? what does asterisk signify, do you think. what do...

well a good rule of thumb is 2^n where n is number of cycles (provided you have a single dsDNA molecule to start with). so after 10 cycles e.g. 1024 molecules, but i don't know if that is sufficient for you...

Well, the fact that the internal volume of a cell increases by the cube of the radius contributes to size limitations, since this is not in line with the increase in surface area, the larger the cell gets the more difficulty it will have obtaining enough nutrients. There are of course ways for cells...

well it seems we are dealing with a hypothetical situation, as the cell has countless mechanisms in place to ensure the cell goes through the cycle in the correct order. it goes without saying that a cell with no nucleus would not stay around for very long...

it seems to me the origin of life, assuming you are speaking of the genesis of primitive forms of life like prokaryotes, is a much contested subject with very little real proof. which is why discussions usually end up in creationism debate, in the end it really just comes down to what you believe. T...

would you not just end up with 2 cells, whereof one would be without nucleus?
