proteins correct answer: polymers of amino acids linked in a linear chain by peptide/amide bonds (polypeptides) polysaccharides correct answer: polymers of sugars (mono-saccharides) linked in linear and branched chains by glycosidic bonds DNA correct answer: polymers of nucleotides linked in linear chains by phosphodiester bonds protein enzymes correct answer: Linkages (bonds) are formed/broken by _______? sickle cell anemia correct answer: a single amino acid change in hemoglob...

Which amino acid is not chiral? a. Proline b. Glycine c. Tryptophan d. Histidine e. Isoleucine correct answers b. Glycine Do nucleic acids have a charge at the physiological pH? a. Nucleic acids are positively charged due to phosphate groups in a back bone b. Nucleic acids are not charged molecules c. Nucleic acids are negatively charged due to phosphate groups in a back bone d. Sugars in nucleic acids are positively charged, so nucleic acid molecules are negatively charged correct a...

The lipase-mediated release of fatty acids can always be expected to occur when a person is correct answers running from a bear. The role of glycogenin is to correct answers serve as the origin of the glycogen polymer. Which particles transport triacylglycerols to adipose tissue for storage? correct answers chylomicrons Order the following steps in glycogen particle synthesis. The glycogen synthase activity of glycogenin uses UDP-glucose to extend the chain up to 7 residues. The g...

What is the D configuration of a sugar in a Fisher projection? - chyrol carbon furthest from the carboxyl group hydroxyl on right What is the L configuration of a sugar in a Fisher projection? - hydroxyl on left What is the difference between glycogen and amylopectin? - glycogen- has branches about every 10 residues (more highly branched) amylopectin- has branches about every 25 What is amylose made up of? - glucose What makes up starch? - amylose amlyopectin What is a gly...

Order the following steps in glycogen particle synthesis correct answers 1- The glycosyltransferase activity of glycogenin adds UDP-glucose to a tyrosine residue in glycogenin. 2- The glycogen synthase activity of glycogenin forms an α-1,4 glycosidic bonds that adds UDP-glucose to an O-linked glucose residue. 3- The glycogen synthase activity of glycogenin forms an α-1,4 glycosidic bond that adds UDP-glucose to an O-linked glucose disaccharide. 4- The glycogen synthase activity of glycogeni...

What happens during non competitive binding? - binds at allosteric site How are peptide bonds formed? Broken? - dehydration synthesis hydrolysis What is the tertiary structure of a protein? - 3D structure including bending from hydrophilic/hydrophobic interactions R groups What is the quaternary structure of a protein? - interactions between different polypeptide chains in proteins composed of more than one polypeptide (subunit interaction) How are carbohydrates broken down into CO2? - ox...
