Suppose that the cell shown in this figure is secreting insulin, a protein hormone, via exocytosis. which statement most accurately describes why this mechanism of transport is ideal for insulin secretion?

Proteins are large molecules that cannot be transported efficiently across the membrane via transport proteins.

Explanation:

Insulin is a protein hormone or a peptide hormone.

                      The pancreas in the body secretes insulin hormone. Insulin hormone is used to absorb the glucose or sugar from the carbohydrates that are provided from the food we eat in the form of energy for our body. This energy is used by the body to perform different functions. Insulin also stores this energy for future use.

                      Pancreas secrete insulin by the process of exocytosis. It is a transport process where the cell transport molecules through a energy dependent process.

Thus the answer is

Proteins are large molecules that cannot be transported efficiently across the membrane via transport proteins.

you should think about the answers you give and expect the same form your questions.
