The given blank space in the statement, “In active transport, ATP provides energy to transport a substance ____________ a concentration gradient.” Introduction: The mechanism of membrane transport in living beings is very important. They are classified either as passive or active transport, based on the energy requirement. The mechanism during which the movement of substances occurs across the concentration gradient and the membrane, without the involvement of direct energy input, is passive transport.

9) Below, there is a representation of an SDS-PAGE gel. Assuming the samples in the MW standard have masses of: 66 kDa, 45 kDa, 36 kDa, 29 kDa, 24 kDa, 20.1 kDa, and 14.2 kDa, a) Figure 4: indicate where each of the measurements were taken and label as in II.6. figure 2 above. b) As in II.7. Table 1 above create Table 2 using the data below. Determine the r.f. values for the MW standards, plot the relative mobility versus the log of the mass for the standards, and use the best fit straight line to determine the molecular weights of the proteins in the whey, peak 1, and peak 2 lanes.
