b) The acidic conditions break down foods directly.

c) It allows for the activation of pepsinogen into pepsin.

Explanation:

The acid inactivates all the enzymes in the food, and begins its own function of breaking down what is left of the food in combination with the enzyme pepsin. Finally, this nutrient rich food concentrate moves in the small intestine. There the acid is neutralized and enzymes produced by the pancreas are reintroduced to complete the process.

Answer from: Molly666

All of these choices are correct-d

Explanation:

Low pH of the stomach is effective because enzymes like Pepsin, break down food and work best in an acidic environment in the breakdown of proteins Also, a low pH stomach acid also triggers the release of other digestive enzymes from the pancreas, which also help break down carbohydrates,

The mechanism is such that Because most proteins start digestion in the stomach, the stomach cells secretes the zymogen pepsinogen which by activation by HCl in the stomach forms the Pepsin that break the peptide bond of amino acids helping digestion.

Low pH in the stomach, ie Gastric acid with a pH of less than 3 provides an unsuitable environment for for bacteria and parasites by killing them and preventing them from reaching the intestines which would have been responsible for many more illnesses.

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
