Question 2: You have just discovered a new enzyme that catalyzes the degradation of cellulose to glucose. You hope to commercialize this enzyme ultimately to invent a process for biofuel manufacture. In order to determine how efficient the enzyme is and how fast the enzyme catalyzes the reaction, you have to perform some basic enzyme kinetics. Plot the following enzyme data for the enzyme catalyzed reaction and determine the Km and Vmax. Show your graph with correct units on the...

A.Your summer research project is to study the kinetics of a newly discovered enzyme. You have already identified the substrate and optimal reaction conditions. Propose how you would set up experiments to characterize the maximum velocity (Vmax) and Michaelis constant (KM) of this enzyme, assuming that it will display Michaelis-Menten kinetics. B. How would you compare the specificity of the enzyme for its natural substrate versus its specificity for a chromogenic substrate analog that was synthesized in the lab

Imagine that you have a large and sudden craving for Krispy Kreme doughnuts, so you purchase a box filled with 10 colorful doughnuts and while you are binge watching your favorite show, you managed to eat all 10 of the doughnuts. Now that have you ingested large amounts of sucrose, the glucose and fructose that exceed caloric requirements are transformed to fatty acids for triacylglycerol synthesis. This fatty acid synthesis consumes acetyl-CoA, ATP, and NADPH. How are these substances produced...

If a cell does not have mitochondria, it cannot harvest the entire energy stored in a molecule of glucose? A)True B)False Phosphofructokinase is an enzyme that is important for the breakdown of the glucose molecule to generate ATP. In regards to that, when the ATP levels are high, the phosphofructokinase is inhibited. What do you expect to happen to the enzyme when the levels of ATP within the cell drop? 1.The enzyme will be activated. 2.The enzyme will be deactivated....

This last set of questions builds on the previous series. You have purified an enzyme catalyzing a disulfide exchange on keratin polypeptides and is called KDI (keratin disulfide isomerase). In order to simplify the protein sequencing, you try to split the protein into large fragments first. You can do this by adding a little bit of subtilisin, a protease that is nonspecific but will cleave unstructured regions. When you do this, you get 2 polypeptides: -8 kDa &-33 kDa. The...
