α-helices and β-sheets are primarily stabilized by which of the following interactions? correct answer: hydrogen bonding Domains are common structural elements that retain a particular function within the protein. Which of the following is an example of a protein domain? correct answer: An arrangement of β-strands connected by α-helices (βαβαβ) How do most enzymes reduce the activation energy needed to move a reaction forward? correct answer: Providing an active site most compl...

True or false: Generally, the total number of nonpolar amino acids has a greater affect on protein structure than the exact order of amino acids in a polypeptide chain. - CORRECT ANSWER-False. The order in which amino acids are linked is unique for each protein and is the most important factor in determining the overall protein factor. True or False: The "polypeptide backbone" refers to all atoms in a polypeptide chain, except for those that form the peptide bonds. - CORRECT ANSWER-False...

Phosphorus has an atomic number of 15. This tells us that... - Answer-there must be 15 protons True or False: covalent bonds are stronger than ionic and hydrogen bonds because atoms that are joined with covalent bonds share electrons - Answer-True An e- in a hydrogen atom exists in the first valence shell. The valence e- of Aluminum exist in the 3rd shell. Which valence shell e- have higher potential energy and why? - Answer-the valence e- of aluminum, bc higher e- shells have higher energy...

Which energy-producing process is thought to have come first during cellular evolution? correct answers Glycolysis The initial importance of a membrane enclosing self-replicating RNA molecules and associated proteins was that it correct answers maintained these molecules as a unit capable of reproduction and evolution. Mitochondria and chloroplasts resemble bacteria in that they correct answers have their own DNA, have their own ribosomes, reproduce by simple division into two. Which of...
