Master Photosystems and the Electron Transport Chain fast ⚡ – clear explanations, OCR-aligned.
You’ll cover
• What photosystems are and how antenna complexes and reaction centres capture light energy.
• The structure of Photosystem II (PSII) and Photosystem I (PSI) and how they differ.
• How electrons are transferred between photosystems through the electron transport chain.
• The role of electron carriers and redox reactions in moving electrons along the thylakoid membrane.
• How electron transport contributes to the formation of a proton gradient used in ATP production.
What’s included
• Labelled diagram showing the structure of a photosystem including the antenna complex and reaction centre.
• Labelled diagram comparing Photosystem II (P680 reaction centre) and Photosystem I (P700 reaction centre).
• Labelled diagram showing the structure of the electron transport chain across the thylakoid membrane.
• Labelled diagram illustrating the proton gradient established across the thylakoid membrane.
• Table outlining the components of thylakoid membranes and their roles in photosynthesis.
