From the era before Sanger sequencing was invented.

comment Determining and Differentiating specific ATPases
Yes, but as I said in my answer, you can artificially get F-ATPase to do that, although probably not in the context of cellular compartments.

comment Transmembrane Protein Problem
Ionic bonds and covalent bonds are stronger than hydrogen bonds which are stronger than weak bonds like van der Waals. The term 'weak' isn't usually used in connection with ionic bonds in my experience, which is why I was puzzled.

comment Fermentation to acetic acid
A Google search for "homemade apple vinegar" yields lots of information. Perhaps you will get an answer from an expert here, perhaps not.

comment Why doesn't the cell membrane just… break apart?
Also the bilayer maximises van der Waals interactions between the closely-packed hydrocarbon chains, again contributing to the stability of the bilayer.

comment What is the most critical step of plasmid purification?
@Chris I agree, I was trying to stress to the OP that the whole process should be carried out carefully, which is what you said. Remembering to add antibiotic to the cultures is also critical!

comment What is Colloidal biology and does it have any scientific background?
The WP page on colloids en.wikipedia.org/wiki/Colloid#In_biology has a useful jumping off point (see subheading "In biology"). There is a discussion in the book "A History of Molecular Biology" my Michel Morange.

So, in summary, all of the steps are critical.

Perhaps worth adding that the formation of the bilayer increases the entropy of the water, but the entropy associated with the phospholipids will decrease. The net change in entropy is favourable.

comment What is hTAP?? Please help
You definitely need to add some context - what sentence(s) did you see it in, and where? A Web Of Science search for hTAP in the TITLE field points to "Human thyrotropin-releasing hormone-associated peptide" but that doesn't appear to be relevant. It isn't unusual for acronyms like this to have several meanings.
