comment Are there genes in humans from the common ancestor of all organisms?
The term to look for is 'ubiquitous' (genes/proteins). Apart from glycolysis and ribosome there is nucleotide synthesis and some (but not all) amino acid synthesis. This list is still not complete.

comment What is the difference between orthologs, paralogs and homologs?
I'm aware of convergent evolution, as well as repeating sequence parts. There is also the conservation of domains with respect to non-functional parts. That's why I wrote "in general".

comment Are there any websites offering graphs for the light absorption of different enzymes?
I think the usual lab method is measuring the enzymes' activity by supplying the substrate and measuring how much product is created in what time.

comment Do all mushrooms have the same multicellular ancestor?
I just see you have a 12% accept rate. That means you haven't accepted many answers to your questions in the past. You should do that if you want people to give you answers, at all.

comment If proteins have an overall charge, how do membrane proteins traverse through the hydrophobic region of the plasma membrane?
Also, lipoproteins use covalently bound lipids to anchor to the membrane.

comment Why does non-continuous sleep makes you feel tired?
Yes, but I'm guessing. OTOH, you can be well rested after 1 hour, if you know beforehand (=expect) that it will be short. So, it's more a question of psychology, not biology IMHO.

comment Average number of gene products in (a) eukaryote(s)
Like the number of genes dwindled in the years after 2000 from 100k to 20k, I expect such unconfirmed numbers to get more close to reality in some years, too.
