All solutes in the glomerular capillaries, including sodium ions and negatively and positively charged ions, pass through by passive diffusion; the only exception is macromolecules such as proteins. There is no energy requirement at this stage of the filtration process.

Does glomerular filtration require energy?

Glomerular filtration results in production of about 180 L of glomerular fluid each day. Filtration does not require the expenditure of metabolic energy; rather it is caused by a balance of hydrostatic and oncotic forces. Glomerular filtration rate (GFR) is the most important index of intrinsic renal function.

Is glomerular filtration ATP driven?

False, glomerular filtration is not an ATP-driven process. Rather, this is a passive process that does not require any energy input from the cell. The glomerulus is a porous structure within the Bowman's capsule that will allow molecules below a certain size to pass through - into the kidneys.
