Which of the following is NOT a factor affecting the rate of alcohol absorption?

• A. Time taken to consume the drink.
• B. Ambient temperature of the environment.
• C. Amount consumed.
• D. Food present in the stomach.

Answer: (B)

Alcohol absorption is driven by what happens inside the digestive tract. Most ethanol is absorbed in the stomach and small intestine, and the pace at which it enters the small intestine is the rate‑limiting step. That pace is mainly controlled by gastric emptying, which is influenced by how much you’ve drunk, how quickly you drink, and whether there’s food in the stomach. Drinking a lot at once pushes more alcohol into the stomach and can speed delivery to the absorption sites, while sipping over time spreads out that delivery. Having food in the stomach slows emptying, so alcohol leaves the stomach more slowly and the absorption rate decreases. In contrast, ambient temperature of the environment doesn’t directly change gastric emptying or the mucosal absorption of ethanol, so it isn’t a factor that affects how fast alcohol is absorbed.
