Glucose Uptake

[syked3]

Why is there a higher concentration of glucose inside the cell and a lower concentration of glucose in the lumen of the gut at the start?

[MrNinie1992]

how is that an active process??does the Na+ gradient provide energy???

[madihashabbir]

@MrNinie1992 yar its not Na gradient its glucose that is providing energy so that it is active transport....

[changl72]

This process requires active transport, but not in the form of ATP. Rather, it uses the energy energy gradient of Na+ to move glucose against its concentration gradient.

[lemcgill1]

I thought it took two Na+ for every glucose molecule to be transported (per my A&P textbook)...

[danmx]

Does this require energy? or is it through passive transport?

[opolip001]

@danmx This requires energy, it is an example of secundary active transport

[cesc0817]

@danmx it use the free energy of concentration gradient of Na+, this is active transport.

THANKS. finally understand how a secondary pump works.
