BIOLOGY- LECTURE 9
Why do we need oxygen for cellular respiration?
-Because its the final electron acceptor in the electron transport
chain
Glygolysis- happens in the cytoplasm
Being made in Glycolysis: NADH, pyruvate, a little bit of ATP
Two types of Fermentation:
Lactic acid fermentation: produces lactate
Alcohol fermentation: sugars are converted into cellular energy
(yeast)
PHOTOSYNTHESIS:
autotrophs: make their own food through photosynthesis
(plants)- don't usually consume organic molecules from other
organisms
heterotrophs: don't make their own food (animal or human)-
consume other organisms to live
Stoma: makes the oxygen go in and carbon dioxide out
2 stages to photosynthesis:
Light reactions
-occur in the thylakoid membrane
Calvin Cycle
-occur in the stroma of the chloroplasts
products of light reactions are:
NADPH
ATP
Mitochondria: Chloropl
asts:
produces ATP through cellular respiration -
produces ATP through photosynthesis
-C4 plants keep their stomata mostly closed
CAM plants only open stomata at night
-PLANT DO have a mitochondria!
