- You put albumin, the protein responsible for lipid transport through the blood, in methane, a hydrophobic solution. Would you expect albumin to still be functional? Yes the protein would still be functional because its primary structure remains intact Yes the protein would still be functional because it is used to carry lipids No the protein would not be functional because the peptide bonds would be dehydrated No the protein would not be functional because covalent bonds weaken and disrupt secondary structure No the protein would not be functional because the tertiary structure would change to maximize hydrophobic interactionsWhich of the following are polymers? (there may be more than one correct answer.) Amino acids Nucleotides Proteins Fatty acids Polysaccharides Nucleic acidsWhich of the following statements are true about monomers and polymers?Select all that apply. -Polymers are broken down by the process of dehydration.-Monomers are building blocks for polymers.-Water is required (as a reactant) in hydrolysis.-Nucleic Acids, Phospholipids, and Polysaccharides are all examples of Polymers-Nucleotides, Monosaccharides, and Triglycerides are all examples of monomers
- Which of the following correctly matches a monomer and polymer? amino acid & polypeptide amino acid & polysaccharide steroid & fat monosaccharide & proteinWhich of the following are features of proteins? -they are generally circular molecules. -they are made up of 20 different amino acids. -their synthesis involves the participation of several distinct types of RNA molecule. -unlike DNA, protein never forms a helical structure. -during protein synthesis, the growing chains are extended at the N-terminus More than one answer can be right I am confused please helpWhich of the following statements differentiates structurally albumin (a globular protein) structurally with that of collagen (fibrous protein)? O Peptide bonds in collagen are rigid and fixed, while the peptide bonds in albumin can freely rotate O Collagen possess an elongated shape while albumin resemble a spherical shape The amino acids in albumin are in the L-form while the amino acids in collagen are in the D-form Albumin possess less diverse set of amino acids while collagen can contain a variety of amino acid types

Quaternary structure is unaffected by acids or heat. Quaternary structure is determined by the same interaction that holds an α-helix together. Quaternary structure is how prosthetic groups are held in a protein. Quaternary structure is the position of subunits in the overall structure of a protein. All proteins have quaternary structureOrganic molecules are often assembled by polymerization. Which is an exception to this statement? a protein steroid DNA starch
- Glucose molecules are linked together through dehydration synthesis to form starch. Based on this description, glucose is a __ and starch is a __ polymer; monomer monomer; polymer functional group; monomer functional group; polymerWhich of the following is not a component of a nucleotide? a monosaccharide a phosphate a disaccharide a baseCreate a concept map which the main topic is macromolecules and it branches out to the following topics Water, Carbohydrate, Proteins, Lipids- include cell membranes, Nucleic acids A concept map is a useful strategy to organize and understand the "BIG picture" of a particular concept - this case Biochemistry. Concept maps are usually organized in the following manner... • start with the main topic in the middle a key areas are then placed on the map followed by more specific ideas radiating outwards • connectors (lines/arrows) are used to join each concept on the map connectors are labeled with a word or short phrase that explains the relationship between the connected concepts Good concept maps include colors, pictures and other graphic organizers (symbols, shapes, various fonts, etc) to organize and illustrate ideas. Use your class notes and information presented in D2L to gather the information that needs to be presented on the concept map. The more details and connections you…
