BIOL/CHEM 3362 - BIOCHEMISTRY II EXAM 3 STUDY GUIDE 1. How are the chiral carbons on the glycerol of the trigycerides determined? C1 is the carbon that would lead to S-configuration if its priority was increased. (chapter 8 slide 44) 2. How are the archaeal membrane lipids different from membrane lipids found in bacteria and eukaryotes? They are connected to the enantiomers of the bacteria and eukaryotes glycerol. (chapter 8 slide 49-50), Archaea vs bacteria:snG1P vs snG3P (enantiomers). Bacteri...

membrane-bound organelles - ANSWERSWhat is one characteristic that distinguishes eukaryotic cells from prokaryotic cells? CNS - ANSWERSWhere is pain perceived, neurons in the CNS or PNS? myoglobin - ANSWERSWhat is a substance that holds oxygen in muscles and organs? mRNA - ANSWERSThe destruction of what prevents continuous protein production - that allows the cell to change its protein expression over time? timing - ANSWERSWhat about the expression of an antisense gene is a key featu...

be differences in the "sides" of a cell when we talk about cellular polarity. (3pts) The membranes of cells also show "polarity". Name at least 3 separate characteristics of the membrane in the image below that illustrate polarity 1. Chol 0 Gang SPM OPI TM1 TM2 Acyl cytoplasm 2. (3pts) The blue shaded regions of the membrane are lipid rafts, which show differences in lipid and protein composition from other parts of the membrane. These differences restrict movement of molecules ...

MARYVILLE UNIVERSITY ADVANCED PATHOPHYSIOLOGY NURS 611 TEST STUDY GUIDE EXAM 1: CELLULAR BIOLOGY 1. Mitochondria "Power house" organelle. During cellular respiration, they make ATP molecules that that provide energy for all activity. Need lots of oxygen to function properly. It converts ATP into energy. Without it, anaerobic metabolic pathways will synthesize ATP 2. Ribosomes Where mRNA is translated into proteins = protein synthesis. Contain rna protein. Synthesized in...
