Answer:
True.
Explanation:
Large proteins are regarded as large size molecules , or macro-molecules. And they are known to made up or contain polymers of structural units, which are known as amino acids.
In summary, large proteins are generally known to consist of several distinct protein domains, i.e structural units that fold more or less independently of each other.
Therefore , in this case, the large protein will remain in the capillary, and eventually result to the development of an osmotic pressure difference across capillary walls.
