Lab # 4
Background image of page 2
Objectives for Lab #4: 1. Use homogenization and differential centrifugation to obtain live, functioning chloroplasts. 2. Use DCIP as an artificial electron acceptor to report on the light-driven electron transport activity of these chloroplasts. 3. Determine whether or not the inhibitor DCMU can stop electron transport in chloroplasts

dx dt = Rate of sedimentation = 2r 2 P – ρ m ) x g = velocity r = radius of the particle (size) ρ P = density of the particle. Lead is more dense than plastic ρ m = density of the medium. High sucrose is more dense than low sucrose g = force of gravity used η = viscosity of the medium. Not the same as density Larger particles have a greater sedimentation rate because they have bigger r. Anything that makes the numerator bigger makes the velocity bigger. What will an increase in the viscosity of the medium do to the velocity? What is the velocity if the density of the particle = the density of the medium? Stoke’s Equation
