of surface tension

»Some of the uses of surface tension :-

1) Surface tension allows insects (e.g. water striders), usually denser than water, to float and slide on a water surface.

2) Surface tension is an important factor in the phenomenon of capillarity.

3) Surface tension has the dimension of force per unit length, or of energy per unit area.

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.
