The bacterium responsible for gastric ulcers, Helicobacter pylori, survives the acidic pH of the stomach surprisingly well. It does so in part by synthesizing and excreting large amounts of the enzyme urease, which hydrolyzes urea to bicarbonate and ammonia. Explain how these reaction products lead to a less acidic environment for H. pylori.
