Identify the principal role of cellular respiration
Select one:
a. To convert solar energy into the chemical energy of sugars
b. To convert kinetic energy into the chemical energy of sugars
c. To convert the chemical energy of sugars into the chemical energy that fuels life's processes
d. To convert the chemical energy of sugars into heat to maintain an elevated body temperature
Identify the principal role

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.

the statement is true

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
