Respiration and Photosynthesis
Glucose + oxygen carbon dioxide + water
Glucose Variety of endproducts possible
2 pyruvates (3 carbons)
Lipases split lipids into:
Glycerol (enters cycle at 3PGAL step of glycolysis)
Fatty acids (disassembled 2 carbons at a time to enter the Krebs cycle at Acetyl-CoA step)
Proteases release amino acids which are converted to glycolytic and Krebs Cycle intermediates.
Plants give off oxygen. Does it come from the carbon dioxide or the water???
What happens in hot, dry conditions?
The needs of photosynthesis conflict with need for water preservation.
What happens to Lactic Acid???
What is Oxidized?
What is Reduced?
C6 H12O6 + 6 O2 6 CO2 + 6 H2O
