Final answer:
The statement that alcohol requires no digestion and can enter cells without a specific mechanism is true. Alcohol is absorbed directly into the bloodstream through the stomach and small intestine. Pepsin, however, does not digest cellulose, and glucose can be absorbed without further breakdown.
Step-by-step explanation:
The question addresses whether alcohol requires digestion or a specific mechanism to enter cells. The statement provided is true; alcohol does not require digestion and can enter cells without a specific transport mechanism. Alcohol is absorbed directly into the bloodstream primarily through the walls of the stomach and small intestine. From there, it travels to the liver and other body tissues. Unlike other nutrients, it doesn't need to be broken down and can diffuse across the cell's plasma membrane due to its small size and solubility characteristics.
Referring to pepsin's role, pepsin is an enzyme in the stomach that primarily digests proteins, not cellulose. Therefore, the statement 'Pepsin digests cellulose' is false. Moreover, glucose is a simple sugar that can be absorbed directly by the body's cells without needing further breakdown, which makes the statement 'Glucose can be absorbed by the body without being further broken down' true.
It's important to note that the pH of the stomach is typically very acidic, which helps pepsin and other stomach enzymes in the digestion process. Alcohol, having no need for digestion, bypasses this process and is absorbed as is.
