Aerobic respiration is more efficient in producing energy for
us than anaerobic.
Glycolysis occurs in cytoplasm of cells
Yeast are living cells
Fermentation produces ethyl alcohol, carbon dioxide and
energy
Physical training enables one to carry on aerobic respiration
for longer durations
The source of pain in muscle cells is a build-up of CO2
One molecule of glucose can yield 38ATP as a result of the
process of photosynthesis
And end product of photosynthesis is glucose and water
The electron transport chain transfers energy through the
transfer of electrons
Photosynthesis accomplishes converting chemical bond
energy to solar energy.
Great quantities of ATP are produced in the mitochondria
