For a protein with two ligand binding sites the binding polynomial has the general form: q=[p](1+2k1[l]+k1k2[l]2) where [p] is the unbound protein concentration and [l] is the free ligand concentration. the equilibrium constants are defined as: k1=[pl]/[p][l] and k2=[pl2]/[pl][l]
a. assume k1=k2=k=10 and [l]=0.15. calculate the fraction of sites bound fb
b. consider a model where k1=αk and k2=k . if k = 10 and [l] = 0.15 as before, calculate the binding fraction is α=0.1

1134567 a jet with mass m = 1.1 ă— 105 kg jet accelerates down the runway for takeoff at 2 m/s2. 1) what is the net horizontal force on the airplane as it accelerates for takeoff? 2.2*10^5 n your submissions: 2.2*10^5 computed value: 220000submitted: saturday, january 26 at 2: 41 pm feedback: correct! 2) what is the net vertical force on the airplane as it accelerates for takeoff? 0 n your submissions: 0 computed value: 0submitted: saturday, january 26 at 2: 41 pm feedback: correct! 3) once off the ground, the plane climbs upward for 20 seconds. during this time, the vertical speed increases from zero to 21 m/s, while the horizontal speed increases from 80 m/s to 95 m/s. what is the net horizontal force on the airplane as it climbs upward? n 4) what is the net vertical force on the airplane as it climbs upward? n 5) after reaching cruising altitude, the plane levels off, keeping the horizontal speed constant, but smoothly reducing the vertical speed to zero, in 13 seconds. what is the net horizontal force on the airplane as it levels off? n 6) what is the net vertical force on the airplane as it levels off?
