Question

Scientists are testing substance L to determine how it enters mammalian cells in a culture. The cells maintain a 120 millimolar (mM) intracellular concentration of substance L. The scientists determined the rate of entry of substance L into the cells at various external concentrations of substance L (10 to 100 mM) in culture medium (Table 1). Table 1. Rate of entry of substance L into mammalian cells in culture External concentration of substance L (mM) Rate of entry of substance L into cell as a percent of maximum 10 5% 20 25% 30 45% 40 65% 50 80% 60 90% 70 95% 80 100% 90 100% 100 100% The cells maintain substance L at an internal concentration of 120 mM. (C) Predict the likely effect on the ability of substance L to enter the cells of substance L is attached to a large protein instead of free in the culture.
