You're on the pilot episode of a new reality show called "the transport factor." the host hands you three different amino acids, four different sugars, and two different ions. then the host shouts, "how many different proteins does the cell need to move these molecules across the plasma membrane using facilitated transport?

9 (Nine)

Explanation:

The host has handed you three different amino acids, four different sugars, and two different ions which totals up to 9 (nine) molecules. These molecules now need to be transported across the plasma membrane using facilitated transport which is done by proteins. One protein can carry one molecule across the plasma membrane and therefore, it would require nine proteins to transfer nine molecules across the plasma membrane.
