Bacteria cytoskeleton

Yes, Virginia. There is a bacterial cytoskeleton.

Lipid Metabolism: tough but fun

I was asked in class today about lipid metabolism and I shined the answer because I didn’t want to get into all the ins and outs and whathaveyous, but this forum will give me the chance to address it in a more manageable manner.

Fatty Acid Biosynthesis

This page is from a faculty member of the Indiana University’s School of medicine and in it he describes lipid biosynthesis pretty well. Scroll down to the matrix-cytosol figure and you’ll get an appreciation of the intricate network involved in this biology.

Another good source of information is here.

Simply put, it’s not trivial; it occurs in the cytoplasm, in/adjacent to the mitochondria, and also at the ER.
We’ll delve much more deeper into the biology when we discuss coupled metabolic pathways.

CH385 Lessons 1 and 2

The heart of this 2-class block is learning some of the terminology to distinguish between the major classes of cells. We have Prokaryotes (eubacteria and archae) and Eukaryotes (protozoans, or single-cell euks and metazoans, or multi-cellular euks).

EOH Quiz batter up, WPR on deck

Quiz:

Know IGE and GGE forwards and backwards. Remember that the relationship between a gas and dissolving that gas into water is the moles (they don’t change… see the video below).  Also remember the partial pressure problems – know Dalton’s law of partial pressures.

Know the basic thermo and Hess law terms (define/apply) and a basic problem.

WPR:

Think the Quiz plus 2 lessons (explosives). We have the calorimetry lab in class (I’ll demo it this week: add 2 M NaOH and 2 M HCl together and monitor temperature). If you max the quiz, you’ll have the majority of it covered. If not…
