HKDSE Biology - Photochemical reactions and Carbon fixation
Compulsory Part I Cells and Molecules of Life
Photochemical reactions 🍀
👆🏻This photo showing the steps in photochemical reaction including light absorption, photolysis of water in the generation of NADPH as well as generation of ATP.
🔺Photochemical reaction takes place in the thylakoid membranes of grana.
1. Light absorption
2. Generation of NADPH
3. Generation of ATP
HKDSE Biology students have to remember what is being generated in photochemical reaction ❗️ ❕O2, ATP and NADPH
Calvin cycle 🍀
👆🏻This photo showing the steps in carbon fixation - Calvin cycle.
🔺Carbon fixation takes place in the stroma
1. Carbon fixation
HKDSE Biology students have to remember what is being generated in Calvin cycle ❗️ ❕Glucose, ADP and NADP+
👆🏻This photo showing the linkage between photochemical reaction and Calvin cycle.
That's the end of this topic 👏🏻
