Answer: One enzyme can speed many types of chemical processes Not true. Enzymes are very specific. Enzymes are not sensitive to temperature. Not true. Enzymes are proteins. They denature (lose 3 dimensional structure) at high temperatures. Enzymes typically work independently of vitamins and minerals Not true. Enzymes often require minerals or vitamins. This is the true one: Enzymes that work in the acidic environment of the stomahc cannot work in the basic or alkaline environment of the small intestine and vice versa. This is why the digestive enzymes from your stomach don't digest your intestine. Enzymes are often pH sensitive.
