  2. Carbohydrase - Wikipedia

    en.wikipedia.org/wiki/Carbohydrase

    Carbohydrase is the name of a set of enzymes that catalyze five types of reactions, turning carbohydrates into simple sugars, from the large family of glycosidases. [ 1 ] Carbohydrases are produced in the pancreas , salivary glands and small intestine , breaking down polysaccharides .

  3. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    During the first phase, it requires the breakdown of two ATP molecules. [1] During the second phase, chemical energy from the intermediates is transferred into ATP and NADH. [2] The breakdown of one molecule of glucose results in two molecules of pyruvate, which can be further oxidized to access more energy in later processes. [1]

  4. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    The liquid quality of the saliva will help in the softening of the food and its enzyme content will start to break down the food whilst it is still in the mouth. The first part of the food to be broken down is the starch of carbohydrates (by the enzyme amylase in the saliva).

  5. Digestive enzyme - Wikipedia

    en.wikipedia.org/wiki/Digestive_enzyme

    Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids. Protein digestion, therefore, primarily starts in the stomach, unlike carbohydrate and lipids, which start their digestion in the mouth (however, trace amounts of the enzyme kallikrein , which catabolises certain protein, is found in ...

  6. Digestion - Wikipedia

    en.wikipedia.org/wiki/Digestion

    Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes.

  7. Metabolism - Wikipedia

    en.wikipedia.org/wiki/Metabolism

    Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...

    On its own, seltzer does not have minerals and is naturally sugar- and calorie-free. However, many seltzer water brands do have added flavorings or sweeteners, such as natural fruit essences ...

  9. Extracellular digestion - Wikipedia

    en.wikipedia.org/wiki/Extracellular_digestion

    During extracellular digestion, food is broken down outside the cell either mechanically or with acid by special molecules called enzymes. Then the newly broken down nutrients can be absorbed by the cells nearby. Humans use extracellular digestion when they eat. Their teeth grind the food up, enzymes and acid in the stomach liquefy it, and ...
