Re: Food to ATP energy?

... this reply is going to be a little bit Math-intense, but I'll try to summarize at the end (I think I answered the bulk of your issue above): The molecular weight of glucose is ~180 grams/mol. That means one mole of glucose weighs 180 grams. One mole of glucose could, at 100% efficiency (theoretical ...

Help: Confused with primers in a PCR of a vector?

Hi guys, I am an undergrad being introduced to a lot of different lab techniques, so I'm not entirely familiar with what is going on. We recently ligated a gene into a pBS vector and popped it into some E. coli cells. We looked for positive clones via blue/white screening and isolated/purified the r...

Reasons why spontaneous human combustion is impossible?

... would need 163*42 = 6.8 kJ OK, here I found the body contains 0.25 kg of ATP http://en.wikipedia.org/wiki/Adenosine_triphosphate The MW is 507 g/mol, which means we contain about 0.5 mol. That would mean release of 15 kJ. Well, maybe I should reconsider my conclusions... :-D

How do i know if a reaction is endothermic or exothermic?

Consider the Reaction: 2Hg) (s) --> 2Hg (l) + O2 (g) Bond: Hg=O 340kJ/mol O=O 498 kJ/mol How do i solve this? My answer was exothermic but it was wrong. It should be endothermic. This is how i solved it: Enthalpy Before: 2(340) = 680 Enthalpy After: 498 Change ...

Re: Why is ATP rather than GTP, CTP or TTP the energy currency?

... protein synthesis ( almost all of them CTP-GTP-TTP and ATP have same Bond energy . All nucleoside triphosphates have ΔG°' values close to -31 kJ/mol ) thermodynamically . Slow speed and accuracy for error check is utmost important in `Structural synthesis ` of proteins . BUT when the FASTER reaction ...
