It is clearly visible from the graph that initially, the rate of diffusion increases with an increase in the number of glucose molecules until the plateau is reached. So, the answer is C
The coated vesicles does not become a part of the endoplasmic reticulum. So, the false statement is D

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...

33) Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of an animal? A) Sodium and glucose bind to the same site on the cotransporter. B) Transport of glucose against its concentration gradient provides energy for uptake of sodium ions against the electrochemical gradient. C) Sodium ions can be transported whether or not glucose is present outside the cell, but glucose transport requires cotransport of sodium ions. D)...

Are the following statements true or false? 1. Membrane carbohydrates occur as either glycoproteins or glycolipids, and most always face away from the cytosol. 2. The melting temperature of a phospholipid bilayer increase with an increased content of unsaturated fatty acid. 3. Molecules which permeate a plasma membrane by facilitated diffusion require cells to use energy (ATP) for their transfer. 4. “Catabolism” refers to synthetic processes that occur inside the cell. 5. Type I collagen has a membrane bilayer-spanning domain....
