Why is ti advantageous for a cell to expend metabolic energy to polymerize gulucose molecule.?
Consider the proteins in Figure 1. Assume they are treated with chymotrypsin to cut them into fragments, and then the fragments are separated by gel electrophoresis. What would the fragment patterns look like in the gel for the three different proteins, assuming we can separate polypeptides that differ in size by very small amounts? Complete Figure 2 below to show the location of the uncut polypeptides (- enzyme lanes) and the cut fragments (+ enzyme lanes).

- Explain how these mechanisms affect protein diversity.arrow_forwardA single polypeptide chain houses the transferase and debranching enzyme. Cite a potential advantage of this arrangement.arrow_forwardMany enzymes are switched "on" by attachment of a phosphate group at a specific serine somewhere on the protein (phosphorylation). The basic reaction is: E + ATP2 Ep + ADP Po SERINE PHOSPHO SERINC (Note the "squiggles" before the backone amide and carbonyl indicate the polypeptide chain continues on either side of the serine). For phosphorylation to have this effect, there has to be some equilibrium between inactive and active forms conformations of the enzyme: [Eactive] [Einactive] Einactive 2 Eactive; K* The same basic equilibrium must exist for the phosphorylated protein: [Ep,active] [Ep,inactive] EP,inactive 2 Ep,active; Kp = (a) If phosphorylation increases the measured activity of the enzyme, is K* or K larger? Why? (b) Does the phosphorylation site need to be near the site where the enzyme binds its substrate (e.g. the reactant whose chemistry it catalyzes)? Why or why not?arrow_forward

Use your Amino Acids Reference Sheet to complete the following table. Fill in the blank spaces of each row with either the missing DNA triplet, the mRNA codon, or the Amino Acid. While there are actually multiple codons that code for any one amino acid, for this activity there only needs to be one DNA triplet and one corresponding mRNA codon recorded for each amino acid.
