respiration Flashcards
use of energy in living organisms
muscle contraction, protein synthesis,
cell division, active transport, growth, the
passage of nerve impulses and the maintenance of a constant body temperature
what happens to yeast resipration when temp increase
increases until optimum then enzymes denature killing yeast
aerobic resipration
chemical reactions in cells that use oxygen to break down nutrient molecules to release energy
word equation aerobic resipration
glucose + oxygen → carbon dioxide + water
chemical equation aerobic resipration
C6H12O6 + 6O2 → 6CO2 + 6H2O
anaerobic resipration
chemical reactions in cells that break down nutrient molecules to release energy without using oxygen
word equation anaerobic resipration in yeast
glucose → alcohol + carbon dioxide
word eqaution anaerobic resipration in muscles
glucose → lactic acid
chemical equation anaerobic resipration in yeast
C6H12O6 → 2C2H5OH + 2CO2
what happens during vigurous exercise
State that lactic acid builds up in muscles and blood during vigorous exercise causing an oxygen debt
what happens to fix oxygen dept
(a) continuation of fast heart rate to transport
lactic acid in the blood from the muscles to
the liver
(b) continuation of deeper and faster breathing
to supply oxygen for aerobic respiration of
lactic acid
(c) aerobic respiration of lactic acid in the liver
