Question

3 nate 0 Some proteins are embedded in the nonpolar phospholipid bilayer of a cell membrane. How would you expect the three-dimensional structures of these proteins to differ from phycocyanin and other water-soluble proteinse 7 Determine whether each statement below is true or false. Explain your reasoning. a. Two different proteins may be generated from the same number and type of amino acids. True False b. Enzymes that break down proteins into their constituent amino acids catalyze the process of denaturation True/False c. No covalent bonds are ever disrupted during protein denaturation. True/False suotin deinturation now couglont houd lille hydrogen bonding louna.

Answer 1

6. The presence of such proteins, embedded in the non polar phospholpped bPlayer of a cell membrane; makes the cell membrane more functional such that they act as receptors that bind to external no. of molecules. head These proteins are arranged within the membrane with the polar towards the outside and hydrophobic tarts towards thside. Hydrophilic layer" cell Hydro philic head membrane f e ) 4 Hydraulic head boerde "phospholipids - Proteins Hydrophobic Fatty add talls Hydro Iphobic layer M These protone are embedded into the cell membrane, such that the tails of phospholipids are in contact with the protons embedded making them water insoluble proteins.

7a) True. - Two different protuns may be generated from the same number and type of amuno auds, because . anum ands sequence will differentiate one protan from another protun. Amuno and Sequence talde in protein inove great importance in living 6) False :-( Enzyme are Biocatalyst and it activate the proteen released recutions and it will not distury. the protun so, the answer is talge" c) Fase - when the native firm of a protein y subjected to change in temperature of change in pH, then the hydrogen bonds are distrubed, due to this globules untold and helix gets uncorted and prot un looses its bidugical activity. Hence, "no Covalent bonds are ever disrupted during protein denaturation is a false statement - DE please rate my Anmer
