fill in the blank question
the transport maximum is dependent upon the number of in the epithelial cell membrane.
need help? review these concept resources.

Explanation:

Transport maximum ($T_m$) in renal physiology (a part of Medicine and Health sub - field of Natural Science) is related to carrier - mediated transport. Carrier proteins in the epithelial cell membrane are responsible for transporting substances (like glucose in the proximal convoluted tubule). The number of these carrier proteins limits the rate of transport once they are saturated.

Answer:

carrier proteins
