cellular respiration
the process by which plant and animal cells obtain energy from glucose (food)
Where stage 1 of cellular respiration occurs
cytoplasm of the cell
Where stage 2 of cellular respiration occurs
mitochondria
Stage 1 of cellular respiration
molecules of glucose are broken down into smaller molecules- very little energy is released
Stage 2 of cellular respiration
small molecules are broken down even more using oxygen; large amounts of energy is released
raw materials for rellular respiration
glucose & oxygen
glucose
product of photosynthesis
fermentation
cells release energy from food without using oxygen
alcoholic fermentation
fermentation that occurs in yeast and other single-celled organisms to produce alcohol, carbon dioxide, & a small amount of energy
lactic acid fermentation
fermentation that occurs due to cells lacking oxygen; energy is produced by breaking down glucose without using oxygen
