Which gas prevents the spread of fire and extinguishes it? is a type of compressed gas that prevents the spread of fire and extinguishes it.

carbon dioxide

Explanation:

The carbon dioxide is a gas which can prevent the spread of fire and extinguishes it. It is a gas which is used in an active fire extinguisher device which is used for extinguishing fire in the emergency cases. The carbon dioxide gas restricts the combustion of the fuel by the oxygen. It is filled in the  fire extinguishing cylinders with force and compression so that when it released it exert some pressure over the burning site to stop the fire.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
