respiration Flashcards
what are the uses of energy in the body?
active transport, nerves, muscles
- muscle contraction
- protein synthesis
- cell division
- active transport
- the passage of nerve impulses
- maintenance of a constant body temperature
what is respiration?
the chemical process whereby glucose is broken down to release energy
what is aerobic respiration?
the chemical reactions in cells that use oxygen to break down nutrient molecules to release energy
what is the word equation for aerobic respiration?
glucose + oxygen → carbon dioxide + water (+energy)
what is the chemical equation for aerobic respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O
what is anaerobic respiration?
the chemical reaction in cells that break down nutrient molecules to release energy without using oxygen
what is the word equation for anaerobic respiration?
glucose → carbon dioxide + alcohol (+energy)
what is the chemical equation for anaerobic respiration?
C6H12O6 → 2CO2 + 2C2H5OH
what are the disadvantages of aerobic respiration?
it builds up lactic acid. which is toxic and causes cramps and aches if it builds up
what is oxygen debt?
it is the extra amount of oxygen that is needed to break down lactic acid completely in the liver
what are the uses of yeast
- bread making
- fermenting wine
- brewing beer
is aerobic respiration more efficient than anaerobic?
YES
does anaerobic respiration break down glucose completely?
NO
