Question

Assertion : Glomerular filtration requires expenditure of energy by kidney
Reason : Glomerular filtration occurs because pressure in the glomerular capillaries is lower than the pressure in Bowman's capsule

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

Glomerular filtration occurs because the pressure of the blood flowing in the glomerular capillaries is higher than the pressure of the filtrate in Bowman's capsule. In other words, blood pressure drives glomerular filtration, and because the process takes advantage of a pressure gradient, glomerular filtration does not require the expenditure of energy by kidney cells
