The next generation of engineers and scientists was already working on the next breakthrough – the development of personal active transporters, capable of transporting individuals across vast distances in the blink of an eye. The possibilities were endless, and the future was brighter than ever.

The SGLT will stop. Even though it uses an indirect gradient, that gradient collapses when the Na⁺/K⁺ ATPase (primary) stops due to lack of ATP. GLUT1 will continue working until the glucose gradient equalizes.

If a cell is treated with a poison that stops ATP production (cyanide), which will stop first: a sodium-glucose symporter (SGLT) or a simple glucose uniporter (GLUT1)?

But life doesn’t always have the luxury of going with the flow. Sometimes, cells need to move molecules uphill —against the current.
