Question

Which is not a function of proteins? Storage of genetic information. Membrane transport. Muscle contraction. Catalysis. The a-helix and beta -sheet are alike in that Both are examples of tertiary structure. Both are found in all proteins. Both are held together by hydrogen bonds between backbone groups. Both have all side chains oriented in the same direction. The bond joining the amino acids in a protein's structure is A peptide bond. A disulfide bond. A Hydrogen bond. An ionic bond. Myoglobin performs its oxygen-binding function better than heme alone because The protein around the heme enables bound oxygen to oxidize the iron. Protein bound heme binds carbon monoxide more weakly than does heme. Protein-bound heme has a higher oxygen affinity. The protein around the heme is mostly polar residues that hold the heme place by hydrogen bonding. Enkephalin is Tyr- Gly- Gly -Phe-Met. Which statement about enkephalin is true Enkephalin is a tetra peptide. Enk

Explanation / Answer

Q5.

Storage of genetic information ---> this is not a function, since that is DNA

membrane transport --> yes, it uses proteins

muscle contractions --> muscles are build up by protein

catalysis --> many enzymes are proteins

Q6

a) false, they are not tertairy

b) false, they are not in proteins

c) true, they are allike in that they are both held together bu H-bonds

d) not lreally, that is the alpha/beta notation

Q7

The peptide bond is a specific bont which bonds amino acids + proetins
