1.	Which of the following is released by JG cells when GFR falls its normal levels?(a) Renin(b) Rennin(c) Lipase(d) ADHI got this question during a job interview.My question comes from Mechanism of Concentration of the Filtrate topic in section Excretory Products and Elimination of Biology – Class 11
Answer» The correct ANSWER is (a) RENIN To elaborate: A fall in the GFR can activate the JG cells to produce renin which CONVERTS angiotensinogen in the blood to ANGIOTENSIN I and further to angiotensin II which is a powerful vasoconstrictor itself and increases the GFR.
