If you need to write this down for an exam, here is how the story translates to the science:
It means active transport is saturable —give the pump too much cargo, and it can’t work faster (unlike passive diffusion, which keeps speeding up with higher concentrations). This creates elegant biological bottlenecks that regulate everything from heartbeat to hormone secretion. 3 characteristics of active transport
ATP is hydrolyzed directly to power the transport protein. If you need to write this down for
Think of active transport as a dedicated delivery driver pushing packages up an escalator going the wrong way. The cell doesn’t care about the “natural” direction—it needs those ions, sugars, or amino acids exactly where they’re scarce. 3 characteristics of active transport
