the sun is the most powerful, reliable energy source available on earth. as photovoltaic cells become more efficient, solar power is becoming a more realistic option for supplying our energy needs. fill in the blanks in the sentences below about photovoltaic cells.

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.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

true is the
