SAT Subject Biology Practice Question 280: Answer and Explanation
10. Structure where most digestion and absorption of nutrients occurs
A. Small intestine
B. Large intestine
Correct Answer: A
A Most digestion and absorption occur in the small intestine. A very small amount of digestion (starch only) takes place in the mouth, and a very small amount of digestion takes place in the stomach (acid hydrolysis of food and some protein digestion). As with Questions 7-9, Questions 10-12 require the same type of knowledge-memorization of basic facts.
