- QUESTION NO.1which of the following are chemical characteristics of monosaccharides? A. They contain multiple hydroxyl groupsB. they contain an aldehyde or ketone group C. They contain a branching carbon backbone D. They contain a carbon-carbon double bond E. Every carbon in a monosaccharide is fully reduced F. Every carbon in a monosaccharide is a chiral centerQUESTION NO.2 glucose absorption is hindered by _________ deficiency A. Retinol B. Thiamine C. Potassium D. Sodium E. Ascorbic acid F. Calciferol QUESTION NO.3 phospholipids is made primarily from A. L-glycerol 1-phosphate B. L-glycerol 3-phosphate C. D-glycerol 3-phosphate D. -glycerol 1-phosphate E. sn-glycerol 1-phosphate F. sn-glycerol 3-phosphateQuestion 12 Carbohydrates that appear in glycosylated proteins and lipids in the GA include I. N-Acetylglucosamine II. fucose III. mannose IV. galactose I, II, IV only I, II, III only II, III, IV only I, II, III, IVQuestion 11. // Hint: Isoelectric focusing separates proteins based on their pI values, and can separate proteins that only differ by a net charge of ±1.±1. Recall that an amino acid residue with a negatively charged R group has a relatively low isoelectric point (pI) where it has zero net charge. Likewise, an amino acid residue with a positively charged R group has a relatively high isoelectric point (pI) where it has zero net charge. Order from Low pH to High pH

(2) The bond which links the two monosaccharides of a disaccharide together is a peptide bond. (3) Monosaccharides cannot be broken done into simpler units by hydrolysis reactions. Which of the following statements are true? Question No. 2 : Assuming that a strand of DNA has the following sequence: 5'-AACCGGTT-3' What is the sequence of complementary strand of DNA, from the 5' to the 3' direction?QUESTION NO. 1 Cystic fibrosis is a frequent generic disease of Caucasians. The CF gene codes for a protein called the cystic fibrosis transmembrane conductance regulator (CFTR) which functions as a cAMP-regulated chloride channel. The protein has two membrane-spanning domains, two domains that interact with ATP, and one regulatory domain. The most common defect is in the gene for one of the ATP binding domains. The result is a protein that does not fold correctly in the endoplasmic reticulum, is not properly glycosylated, and is nor transported to the cell surface. Rather, it is degraded in the cytosol within proteasomes. Drugs that foster chaperone interaction with the mutant protein are a potential therapeutic approach. Chaperones A. are always required to direct the folding of proteins. B. when bound to protein increase the rate of protein degradation. C. usually bind to strongly hydrophilic regions of unfolded proteins. D. sometimes maintain proteins in an…
