If gastric juice has a pH of 2 0 and black coffee has pH of

If gastric juice has a pH of 2 0 and black coffee has pH of 5.0, which one hydrogen ions in solution? gastric juice black coffee Neither one of them; they both release hydroxyl ions Both release the same amount of hydrogen ions in solution saturated fats differ from saturated fats by _____. the number of fatty acid chains they contain the presence of one or more double bonds in their fatty acid chains the number of glycerol molecules they contain the presence of a phosphate group Which of the following is not true of biological catalysts? They speed up chemical reactions They do not become part of the product. They are used up in the reaction They are enzymes

Solution

Gastric juice (a)will produce more hydrogen ions in solution than black coffee. The solution with more acidic pH will release more hydeogen ions than the solution with low acidic pH. Here the gastric juice has high acidic pH. The unsaturated fatty acids differ from saturated fatty acids by (b) the presence of one or more doublebond in their fatty acid chains. It make the fats liquify at room temperature. The statement (b) they do not become part of the product\" is not true about biological catalysts.
