Which of the following is true in regards to k_cat? K_cat can be determined only if the concentration of enzyme [E] is known K_cat referred to as the turnover number. According to Michaelis-Menton kinetics, k_cat determines the amount of ES complex formation A and B A and C Which of the following can be determined from a Lineweaver-Burk plot? K_M k_cat V_max A and C all of the above Which of the following statement is incorrect about chymopepsinogen? It is a zymogen synthesized and stored in the pancreas a single polypeptide chain of 245 amino acid residues cross linked by two disulfide (-S-S-) bonds is activated in the small Intestine is a single polypeptide chain Which of the following statement is correct about chymopepsinogen activation? Activated by trpsinogen an enzyme cleaves a 15 unit polypeptide from the C-terminal end of chymopepsinogen alpha chymotrypsin is capable of self digestion phi chymotrypsin is an active form of enzyme alpha chymotrypsin consist of four disulfide (-S-S-) bonds Consider this reaction of glycogen with phosphate Glycogen_n + HPO_4^2- rightarrow Glucose -1-phospate + Glycogen_n - 1 What is the rate equation for this single step reaction? Rate = [Glycogen]^n[HPO_4^2] Rate = [Glycogen]^[HPO_4^2-] Rate = [Glycogen]^n [HPO_4]^2- Rate = [Glycogen]_n [HPO^2]_4 None of the aboveExplanation / Answer

24) Consider this reaction of glycogen with phosphate
Glycogen,, + i-wo/- t. Glucose-l-phosphate + Glycogen„i What is the rate equation for this single step reaction?
Rate = k[Glycogen]^n[HPO4^2-]^1------------answer
kcat gives an immediate measure of the reactant generation of item under ideal conditions (immersed compound). The units of kcat are seconds-1. The proportional of kcat can be considered as the time required by a catalyst particle to "turn more than" one substrate atom.
The Lineweaver–Burk plot was broadly used to decide essential terms in catalyst energy, for example, Km and Vmax, before the wide accessibility of intense PCs and non-direct relapse programming. The y-capture of such a diagram is comparable to the reverse of Vmax; thex-capture of the chart speaks to 1/Km. It additionally gives a speedy, visual impression of the diverse types of chemical hindrance.
Chymotrypsinogen is a proteolytic catalyst and a forerunner (zymogen) of the digestive protein chymotrypsin. It is a solitary polypetide chain comprising of 245 amino corrosive buildups. It is orchestrated in the acinar cells of the pancreas and put away inside film limited granules at the zenith of the acinar cell.
It is actuated into its dynamic structure by another compound called trypsin. This dynamic structure is called -Chymotrypsin and is utilized to make -Chymotrypsin. Trypsin severs the peptide bond in chymotrypsinogen between arginine-15 and isoleucine-16.
