- Three different molecules are shown below. The electronegativity of sulfur (S) is similar to the electronegativity of carbon (C). The electronegativity of nitrogen (N) is similar to the electronegativity of oxygen (O). T/F: Molecule 1 only contains nonpolar covalent bonds. T/F: Molecule 1 only contains nonpolar covalent bonds. True False Question at position 3 3 1 point Question at position 3 T/F: Molecule 1 could form a hydrogen bond with another Molecule 1. T/F: Molecule 1 could form a hydrogen bond with another Molecule 1. True False Question at position 4 4 1 point Question at position 4 T/F: Molecule 3 is hydrophilic. T/F: Molecule 3 is hydrophilic. True False Question at position 5 5 1 point Question at position 5 T/F: Molecule 1 is unable to form a hydrogen bond with water. T/F: Molecule 1 is unable to form a…arrow_forwardBiomolecules: What are the building blocks of life? From the smallest single-celled organism to the tallest tree, all life depends on the properties and reactions of four classes of organic (carbon-based) compounds-carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates, Lipids, and Proteins are the 3 building blocks of all living things that we will focus on in this unit. These are called macromolecules (or biomolecules) because they are large molecules. They are responsible for most of the body's structure and functions, including energy storage, insulation, growth, repair, and communication. Simple organic molecules can be joined together to form all the essential biological molecules needed for life. Table 1 shows a sample elephant diet and Table 2 shows a sample lion diet. Using the background information, predict the main function of the macromolecules in their diet. Table 1 Elephant proteins (5) fats (%) alfalfa hay 19.0 grass hay timothy hay Proteins Carbohydrates…arrow_forwardProteins are made from chains of amino acids. The amino acids are joined together by structures called peptide bonds. For this problem, draw all hydrogen atoms explicitly. Part A Draw the dipeptide that results when a peptide bond is formed between the two glycine molecules shown here. (Figure 1) Draw it as it would occur at the pH of most body fluids. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Include all hydrogen atoms and charges.arrow_forward
- Which of the following BEST explains the molecular nature of all organic compounds? Organic compounds such as water, monosaccharides, amino acids, and nucleotides compose the basic A monomers needed to sustain the normal metabolic machinery in cells. Generally speaking, organic compounds are the outcome of chemically bonding hydrogen and carbon atoms, (B) В and possibly others such as oxygen and nitrogen. Only members of Domain Eukarya (eukaryotic organisms) may reveal organic compounds in their cellular and molecular structures. Obviously, organic compounds only exists in the living world whereas, inorganic compounds can only be found in D non-living thingsarrow_forwardWhy are van der Waals interactions and hydrogen bonding important for cells? in detailarrow_forward2.1 INSTRUCTIONS: - Do not copy answers from Google or Bartleby. A plagiarism checker will be used. - Answer all questions as they are connected. QUESTION: Compare and contrast proteins and nucleic acids. What do these biomolecules have in common? Be sure to consider both their structures and their functions. In what ways are they different? Be sure to consider both their structures and their functions.arrow_forward
- Could you write me a paragraph on the importance of bonds and bonding in organisms. Can you use only 1 of these topics: • Monomers and polymers • Carbohydrates • Lipids • General properties of proteins • Many proteins are enzymes • Structure of DNA and RNA • DNA replication • ATP • Water – cohesion • Mitosis • Transport across cell membranes • Cell recognition and the immune system • Digestion and absorption • Mass transport in animals – haemoglobin • Mass transport in plants • DNA and protein synthesis • Mutation and meiosis • Photosynthesis • Nutrient cyclesarrow_forwardMacromolecules are very large molecules created by the polymerization of small units called monomers. Most of the macromolecules are present in everyday life, for instance in food. In the Introduction to Food Macromolecules simulation, you will help your friend determine a healthy diet and investigate the types of macromolecules found in food. By performing a series of biochemistry tests, you will know the content of various food items. * * What are the different forms (i.e., monomers, polymers) of carbohydrates, lipids, and proteins? * What macromolecules do each of the biochemical tests check for? * What would an abundance or deficiency of one of the macromolecules cause to the human body?arrow_forwardIn studying a particular biomolecule (protein, nucleic acid, carbohydrate, lipid), a biochemist needs to separate/ purify it from other biomolecules in the sample. However, looking at the monomeric subunits of a biomolecule, one should have an idea about the characteristics of the molecule that would allow to separate/purify it from other molecules. On what basis can you separate: a. amino acids from fatty acids? b. nucleotides from glucose?arrow_forward
- 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 interactionsarrow_forwardConsider the following statement. “To produceone molecule of each possible kind of polypeptide chain,300 amino acids in length, would require more atoms thanexist in the universe.” Given the size of the universe, do yousuppose this statement could possibly be correct? Sincecounting atoms is a tricky business, consider the problemfrom the standpoint of mass. The mass of the observableuniverse is estimated to be about 1080 grams, give or takean order of magnitude or so. Assuming that the averagemass of an amino acid is 110 daltons, what would be themass of one molecule of each possible kind of polypeptidechain 300 amino acids in length? Is this greater than themass of the universe?arrow_forwardDNA and RNA are examples of which FAMILY of BIOLOGICAL MACROMOLECULES? What are the five specific differences between them?arrow_forward
