AND FADH2
ETC makes 28 or 26 ATP.

Water Reabsorption
Obligatory water reabsorption- 90%
o Water follows the solutes that are reabsorbed
o Mostly in proximal convoluted tubules.
Facultative water reabsorption- final 10%
o Occurs in the distal convoluted tubule and collecting ducts
o Regulated by ADH
Low adh- large volume of dilute urine
High adh- small amount of concentrated urine
Filtrate passes from glomerular capsule to the renal tubule
o Filtration occurs in glomerulus.
o The largest amount of solutes and water reabsorption occur in the proximal convoluted
tubules.
