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: -Therefore, small molecules, such as small proteins, glucose, electrolytes, and water, can go through these layers and are filtered out. But large molecules such as abundant proteins, and cells (red blood cells) cannot cross the glomerulus.
Detailed explanation-3: -Answer and Explanation: The substances that are not filtered through the nephrons are plasma proteins and blood cells as their large size prevents them from crossing the fenestrations of the glomerular filtration membrane.
