Na+-glucose cotransport across the luminal membrane 

Facilitated glucose transport across the peritubular membrane

His design allowed air inside the flasks to be exchanged with air from the outside, but prevented the introduction of any airborne microorganisms, which would get caught in the twists and bends of the flasks’ necks.

If a life force besides the airborne microorganisms were responsible for microbial growth within the sterilized flasks, it would have access to the broth, whereas the microorganisms would not.

He correctly predicted that sterilized broth in his swan-neck flasks would remain sterile as long as the swan necks remained intact.

However, should the necks be broken, microorganisms would be introduced, contaminating the flasks and allowing microbial growth within the broth.
