gastric banding surgery is ___.
a the same as gastric bypass surgery, except that it uses a removable band to reduce the size of the stomach pouch
b similar to gastric bypass surgery in that it reduces the size of the stomach
c similar to gastric bypass surgery in that the connection between the small intestine and the stomach is changed
d different from gastric bypass surgery in that the stomach pouch is much larger in gastric banding surgery

Explanation:

For the first question: Pepsin, the enzyme that initiates protein chemical digestion, is active in the stomach's acidic environment.
For the second question: Gastric banding reduces stomach size (via a band), while gastric bypass also reduces stomach size (creates a small pouch); both aim to limit food intake by reducing stomach capacity.

Answer:

B. similar to gastric bypass surgery in that it reduces the size of the stomach
