Biochem module 4 exam questions and answers verified and updated. Which of the following monosaccharides is a ketose? Dihydroxyacetone Galactose Glucose Glyceraldehyde Idose - correct roxyacetone When two carbohydrates are epimers: One is a pyranose, the other a furanose One is an aldose, the other a ketose They differ in length by one carbon They differ only in the configuration about one carbon atom They react differently with iodine - correct answers.They differ only in the confirmation about one carbon atom - correct answers.D.) alpha-D-glucose and beta-D-glucose Lactose is made from linking galactose and glucose. When this happens, _____. Gas is eliminated An anomeric carbon is formed on carbon-1 Water is released An epimer is formed An aldose is formed - correct is released Amylose and amylopectin are both polymers of: A) α-D-glucose B) β-D-glucose C) Galactose D) Idose E) Maltose - correct answers.A.) alpha-D-glucose Which statement about starch and glycogen is false? A) Both have β-D-glucose monomers B) Both starch and glycogen are energy storage polysaccharides C) Both are homopolymers of glucose D) Glycogen is more extensively branched than starch E) Both have O-glycosidic linkages - correct answers.A.) both have beta-D-Glucose monomers Which monosaccharide is not a six-carbon monosaccharide? Fructose Ribose Mannose Galactose Glucose - correct e The two monosaccharides shown below could best be described as: Anomers Aldoses Ketoses Epimers Pentoses - correct rs Which arrow correctly identifies the atom that will become the anomeric carbon? - correct answers.The first carbon at the top of the Fischer structure Based on the form of the cyclic sugar below in a Haworth projection, which Fischer projection formula could have formed this structure? - correct at the hawthorn projection and create Fischer projections for it The following monosaccharides are covalently bonded. What type of bond unites them? - correct 1-6 vertical and through the downward pointing OH group off of carbon 1 1-4 is just side by side Which statement about cellulose is true? Cellulose is the primary storage polysaccharide of animal cells Cellulose is a highly branched polysaccharide Cellulose is a homopolysaccharide The glucose residues of cellulose contain the same configuration as the glucose residues of amylose Cellulose is an anomer of chitin - correct lose is a homopolysaccharide The polysaccharide cellulose is most chemically similar to: Glycogen Dextrose Glycogen Chitin Starch - correct n Which of the following is the most common monosaccharide on earth? Ribose Cellulose Chitin Sucrose Glucose - correct se The "D" in the D-carbohydrates stands for: Derivation Double Disaccharide 3-dimensional Dextrorotatory - correct orotatory Which compound does not fit the formal definition of a carbohydrate? A. C6H12O6 B. C7H10O7 C. C8H16O8 D. C3H6O3 E. C4H8O4 - correct answers.B. C7H10O7 identify the hemiacetal bond - correct des the anomeric carbon, H, OH, and O in the ring tell the difference between alpha beta and D and L configurations - correct answers.D & L: look at the penultimate carbon L=left D=right alpha and beta. Alpha is the OH on the top of the anomeric carbon Beta is under the anomeric carbon Table sugar is also known as: Sucrose Dextrose Glucose Galactose Glycogen - correct se
