Answer to relevant QuestionsExplain the experiment used to determine the structure of AT Case. What happens to the activity and regulatory activities when the subunits are separated? Explain how phosphorylation is involved in the function of the sodium–potassium ATPase. Explain why the second phase of the chymotrypsin mechanism is slower than the first phase. An enzyme uses NAD+ as a coenzyme. Using Figure 7.19, predict whether a radiolabeled H:– ion would tend to appear preferentially on one side of the nicotinamide ring as opposed to the other side. A membrane consists of 50% protein by weight and 50% phosphoglycerides by weight. The average molecular weight of the lipids is 800 Da, and the average molecular weight of the proteins is 50,000 Da.
