Biological examples (ATP hydrolysis and osmotic pressure)

[Nadya Higgins 3F]

Hi, I was looking through outline 1 and found one of the points we should know is of biological examples such as ATP hydrolysis and osmotic pressure. I was wondering if anyone knew where I could find this information (if it's in the textbook or lecture) or if we should do our own research? Also, it would be great to know how they tie into chemical equilibrium or Le Chatelier's Principle. Thank you!

I saw this too and I believe he briefly mentioned it in one of his lectures in week 2, but I couldn't find anything about it in the textbook readings. I would assume it won't be highly tested on since it was not a main focus of the course so far.

Although this probably won't be tested specifically, it may be useful to know ATP hydrolysis is an exothermic reaction, and thus moves towards the reactants when exposed to heat. I believe this was briefly mentioned in the textbook.

Thanks for the tip!

I would say that you would have to look this up since it was only briefly mentioned in the lecture. I know that ATP hydrolysis requires energy however since you need to break bonds to hydrolyze things which means a positive change in enthaply.

ATP → ADP + Pi
ATP: adenosine triphosphate
ADP: adenosine diphosphate
Pi: phosphate ion
This reaction releases energy.
