Apatient presents with these signs: a wounded finger that has turned black, crackly sound under the skin, and foul-smelling bubbly drainage in the area of the wound. what disease does this indicate?

Answer- Gas Gangrene

Gas gangrene is a potentially lethal form of tissue death. A patient with gas gangrene will present with blackening of the skin (due to necrosis), crackly sound under the skin (known as crepitation), and a foul-smelling bubbly drainage in the area of the wound.

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.
