When a refrigerator stops working, you must check the food temperature. if the temperature of the food is above it must be thrown out.

41 degrees Fahrenheit

Explanation:

According to my research on studies conducted by the FDA on food safety, I can say that if the refrigerator stops working and the temperature of the food goes above 41 degrees Fahrenheit it should be thrown out. This is because germs begin to manifest and multiply rapidly on the food which can cause illness when consumed.

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.
