Detailed explanation-1: -The process of filtration of the blood in the Bowman’s capsule is ultrafiltration or glomerular filtration. Any proteins that are roughly 30 kilodaltons or under can pass freely through the membrane, but cells like platelets and large proteins do not. So, the correct answer is polypeptides.
Detailed explanation-2: -So, the correct answer is ‘Plasma proteins’.
Detailed explanation-3: -The kidney glomerulus is a very specialized structure that functions in filtering blood and retaining essential plasma proteins.
Detailed explanation-4: -Under normal conditions, high molecular weight proteins in the plasma (e.g., albumin and globulin) cannot pass through the filtration membrane due to the effects of the size barrier and charge barrier of the glomerular capillary filtration membrane.
