2.77B -Selective reabsorption of glucose

Edexcel IGCSE Biology

where is glucose reabsorbed?

proximal convoluted tubule

how is glucose reabsorbed?

by active transport

what is a nephron adaptation in the proximal convoluted tubule?

lots of mitochondria to provide ATP for active transport

why can the reabsorption of glucose only take place in the proximal convoluted tubule?

gates to facilitate active transport of glucose are only found in the proximal convoluted tubule

what happens to the glucose that is not reabsorbed?

there is nowhere for the glucose to be reabsorbed so continues in the filtrate and ends up in the urine
