as a lover of the mola, I disagree with the conclusions Scout Burns draws, but give mad points for style and execution. 10/10 Facebook rant. Agree with Bob and other pelagic researchersâ¦ molas are awesome, fast, predators that given their numbers and chosen prey must play an integral role in the open ocean ecosystem.
1 Sodium ions are one of the dominant extracellular ions. 2  Aldosterone increases sodium reabsorption from the filtrate. 3  ADH increases water reabsorption from the nephron, and atrial natriuretic hormone increases sodium loss in the urine. 4  Aldosterone increases potassium secretion in the urine.
Regulation of Na + Reabsorption. The principal regulator of Na + reabsorption is the steroid hormone aldosterone, which is produced in the zona glomerulosa of the adrenal cortex. Aldosterone, like all steroid hormones, works as a transcription factor to alter gene expression in cells.he figure provides an overview of Na + reabsorption along the nephron. In different segments of the renal tubule, there are different proteins (co-transporters, counter-transporters, or channels) on the apical surface of tubule cells that mediate Na + reabsorption.
