- Which of the following is amacromolecule that assemblesinto bilayers?a. proteinb. phospholipidc. nucleic acidd. carbohydrateGlycolipids are nonionic lipids that can orient themselvesinto bilayers as phospholipids do. They accomplish this featalthough they lack an ionic group like that of the phospholipids. Suggest a reason why this is possible.Why chemical structure differences important to both living and non living?
- Consider 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?Describe the structural and functional distinctionsbetween rough and smooth ER.Name the parts of the structure.
- What is one structure that you will never find in a human cell? O cell wall O nucleus O cell membrane O mitochondriaWhich of the following statements regarding hydrogen bonding in secondary structures is true? Both α-helices and β-sheets only use intrachain hydrogen bonds. Both α-helices and β-sheets only use interchain hydrogen bonds. α-helices only use intrachain hydrogen bonds and β-sheets can use either intrachain or interchain hydrogen bonds. α-helices can use either intrachain or interchain hydrogen bonds and β-sheets only use interchain hydrogen bonds.In your everyday life, you have probably noticed thatcertain instruments are ideal for certain situations. Forexample, you would use a spoon rather than a fork to eatsoup because a spoon is shaped for scooping, while soupwould slip between the tines of a fork. The use of idealinstruments also applies in science. In what situation(s)would the use of a light microscope be ideal, and why?
