definition
6CO2 +12H2O -> C6H12O6 + 6O2 + 6H2O
An enzyme-controlled series of chemical reaction that occurs in the chloroplast in plant cells
carbon dioxide + water -(light energy)-> glucose + oxygen + water
Uses light energy to synthesis glucose
Light-dependent
Light-independent
Inputs: H2O, NADP+, ADP + Phosphate
Outputs: O2, ATP, NADPH
Location: grana
Inputs: ATP, Hydrogen ions, CO2
Outputs: glucose (C6H12O6), H2O
Location: Stroma
Relationship between light-dependent and independent relationship
Light dependent reaction generates ATP and NADPH for proceeding light independent reaction. Then, light-independent reactions use those to make glucose and return ADP and NADP+ to the light-dependent reaction.
macro-nutrients (amino acids, glucose, fatty acids) are served as input for cellular respiration. Then, cellular respiration generates ATP from ADP and the generated ATP is used to active transport, muscle contraction, etc...
an enzyme-controlled series of chemical reactions and this reaction requires oxygen
chemical equation
glucose + oxygen -> carbon dioxide + water + energy
C6H12O6 + 6O2 -> 6CO2 + 6H2O + 36-38 ATP
anaerobic respiration
ATP is produced by glucose
respiration with an undersupply of oxygen
glycolysis with fermentation
