Explanation:
4.Fermentation is widely used for the production of alcoholic beverages, for instance, wine from fruit juices and beer from grains. Potatoes, rich in starch, can also be fermented and distilled to make gin and vodka.
Fermentation is also extensively used in bread making. When sugar, yeast, flour and water are combined to form dough, yeast breaks down the sugar and gives off carbon dioxide, which causes the bread to rise. Specialty bread such as sourdough uses both yeast and lactobacilli. This combination gives the dough its stretchy texture and distinctive sour taste.
Lactic acid fermentation is used to flavor or preserve dairy products and vegetables, for example yogurt, sauerkraut, pickles and kimchi.
Acetic acid fermentation can also be used to turn starches and sugars from grains and fruit into sour tasting vinegar and condiments including apple cider vinegar and kombucha.
5.The steps involved in respiration are as follows:
•Pulmonary ventilation or breathing through which atmospheric air is drawn in and carbon dioxide-rich air is given out
•Diffusion of gases across the alveolar membrane
Gaseous transport by the blood
•Diffusion of carbon dioxide and oxygen between tissues and blood
•Oxygen is used by cells for catabolic reactions and resultant release of carbon dioxide
Choose the correct answer:
(1) Alveoli
(2) Mitochondria
(3) Bile
(4) Oxygen (O2)
