Mary takes an antibiotic medication, doxycycline, as an oral antibiotic in order to treat her infection from flesh eating bacteria (V. vulnificus). Doxycycline is a small molecule used to treat infections. After being digested in her stomach, it is absorbed by her bloodstream by diffusion. Then the blood moves to the area of infection, as evidenced by inflammation at the infection site.
The red and white molecules in the image below represent water, the blue molecules represent salt, and the green molecules represent doxycycline.
What type of cell transport is used for doxycycline to get from the bloodstream into the bacteria AND in which direction do the molecules move?
Stem: Doxycycline moves from the bloodstream into the bacteria by _________. The molecules move ______________.
