Hello!

I enjoy Crystal Field Theory as well as SiO2 (quartz). There was that one time though (in ichem) where Alan helped me with a problem set involving Ligand Field Theory, which made me appreciate how symmetry affects bonding.

I am getting quite the dopamine rush now that I, too, can link a URL to text! I've always wanted to know how to do that for some reason. So yay!

At week 7 of the semester at Reed Kollege, Johnathan has "bags under his eyes" [1] due to lack of chipping away sleep debt over the course of those 7 weeks.

A section of "The Avenue of Giants."

I love redwoods. I also enjoy collecting Sikhote Alin meteorite specimens.

General...(re: Bioenergetics article)

Overview section could actually introduce the concept of free energy and/or "types of reactions" (albeit briefly, and link to other Wiki pages so people who want to read in more detail can) because someone reading this page has to first make it through that whole first paragraph /before/ they get they get to read about Gibbs free energy (and that overview paragraph is indeed lengthy).

I think the part about "slow combustion" in the overview is a helpful and interesting conceptualization, though I agree that the mention of the bomb calorimeter is unnecessary (a page to bomb calorimetry could be linked at the bottom with the other "See Also" pages, perhaps).

"Living organisms produce ATP from energy sources via oxidative phosphorylation. The terminal phosphate bonds of ATP are relatively weak..." --> mention the sources of energy explicitly. Also, you've linked us to wiki's ox. phosphor. page but a brief, concise sentence explaining what it is would be helpful.

Honestly the section on cotransport-- I'm sure Krane is happy knowing he's on Wiki but this section is irrelevant (unless an editor makes it clear why cotransport is a fundamental aspect (or consequence, perhaps) of bioenergetics).

Energy homeostasis is super important, I feel like this info could go into the overview instead of at the very bottom-- iInclude this with paragraph on Gibbs free energy.

I agree with others that the overview is vague in areas; a new overview paragraph could potentially start with the concept of energy generally then relate that to biological systems. Then in a new paragraph, introduce Gibbs free energy/ types of energy, then you can discuss how biological systems acquire energy, how it gets used, etc etc. Might post more on this as I think about it more...

Last thing: It seems like the phrase "flux" (as in "energy flux") is common when talking about biochemical pathways that release energy; I think this phrase could be explained then used in this article, as energy flux is an important concept with respect to bioenergetic homeostasis.

1. energy flux [2]

2. "unity" of bioenergetics, links bioenergetics with enzyme- mediated processes [3]

3. bodies are batteries that need recharging [4]

4. i rly want to find a source about how one of the goals of metabolism is to generate reduced electron carriers so they can be oxidized in the electron transport chain and so ATP synthsase can crank out ATP, but that source would probably be really old,.. lol. So I think I can just say this, as it's somewhat common knowledge. That or maybe I can cite Lehninger if I find some section like this in the textbook??

Lehninger citation like [5]
