Respiration and photosynthesis
Photosynthesis
Photochemical reaction
H2O + NADP + ADP --> O2 + NADPH + ATP
requires:
light energy + chlorophyll
stages of photochemical reaction
absorption of light energy by chlorophyll
excitement of electrons
transport of electrons through the electron transport chain (e- acceptor)
Photophosphorylation
NADP --> NADPH
photolysis of water (光解)
H2O --> H+ + OH-

ADP --> ATP
Calvin Cycle
CO2 + NADPH + ATP --> triose phosphate + NADP + ADP
CO2
3C compound
triose phosphate (3C)
NADPH --> NADP
ATP --> ADP + P
5C compound
regeneration of carbon dioxide acceptor
ATP --> ADP + P
glucose
cellulose
cell wall formation
starch
food storage
sucrose
transport in phloem
for releasing energy during respiration
CO2 + H2O --> C6H12O6 + O2
fates of carbohydrates
+phosphate, sulphate, nitrate
20 amino acids
protein
for making enzymes
for food storage
for growth
+nitrate, magnesium
chlorophyll
for absorption of light energy in photosynthesis
fatty acid + glycerol
+phosphate
phospholipid
for cell membrane formation
triglyceride
for food storage
+phosphate, nitrate
nucleotides
nucleic acid
as genetic material eg. DNA
destarch
in darkness
no new starch is formed
starch stored in the leaves is converted to sucrose + glucose
significance: ensure that the starch detected was not formed before but newly formed during the experiment
takes place at
chloroplasts
