Can someone correct my mistakes (practice test)
The molecule shown the accompanying figure is a protein fatty acid steroid phospholipid You disrupt all hydrogen bonds in a protein. What level of structure will remain? primary structure secondary structure tertiary structure quaternary structure What is the term used for a protein molecule that assists in the proper folding of other proteins? chaperonin tertiary protein renaturing protein denaturing protein Nucleic acids are polymers made up of which of the following monomers? amino acid nitrogenous bases nucleotides sugars When forming a nucleic acid hydrogen bonds form between the bases of two nucleotides a covalent bond forms between the sugar of one nucleotide and the phosphate of a second covalent bonds form between the bases of two nucleotides a hydrogen bond forms between the sugar of one nucleotide and the phosphate of a second If you boil living cells, they are not coming back to life. What is true of the biomolecules in those cells? DNA will go back into double strands and can be ready to make products Proteins will renature but some will need to be remodeled Sugars will dissolve the lipid bilayer all of the above All of the following are part of a prokaryotic cell EXCEPT a cell wall an endoplasmic reticulum ribosomes a plasma membrane Which of the following is a major difference between prokaryotic cells and eukaryotic cells? Eukaryotic cells have more organelles than prokaryotes. Prokaryotes do not need or make proteins. Prokaryotes are generally larger than eukaryotes. Prokaryotes have cells while eukaryotes do not. Eukaryotic cell walls are composed of phospholipids peptidoglycan cellulose Eukaryotes don’t have cell walls. Prokaryotes are classified as belonging to two different domains. What are the domains? Bacteria and Archaea Bacteria and Eukarya Archaea and Protista Bacteria and Protista
