I will have mindmaps for all units, unit summaries, full notes, learning statements and pastpaper questions. Unit 3 is mostly complete, I still have to compile the mindmap. Unit 2 mindmap is complete, but the notes aren't well done in written form and Units 1 and 4 are still a mess.

Photosynthesis and cellular respiration. Important key highlights are the processes of photosynthesis, the light dependent- and independent reaction.

Learning statements...
| Learning Statements |
|---|
| The structure of the chloroplast is adapted to its function in photosynthesis. |
| Light dependent reactions take place in the intermembrane space of the thylakoids. |
| Absorption of light by photosystems generates excited electrons. |
| Photolysis of water generates electrons for use in the light-dependent reactions. |
| Transfer of excited electrons occurs between carriers in the thylakoid membranes. |
| Excited electrons from Photosystem I are used to reduce NADP. |
| Light-independent reactions take place in the stroma. |
| (All the equations involved in the light independent and dependent reactions.) |
| In the light-independent reactions a carboxylase enzyme catalyzes the carboxylation of ribulose biphosphate. |
| Glycerate 3-phosphate is reduced to triose phosphate using reduced NADP and ATP. |
| Triose phosphate is used to regenerate RuBP and produce carbohydrates. |
| Ribulose biphosphate is reformed using ATP. |
Section 2 - Cellular Respiration...
Learning Statements...
| Learning Statements |
|---|
| Cell respiration involves the oxidation and reduction of electron carriers |
| In glycolysis, glucose is converted to pyruvate in the cytoplasm. |
| Phosphorylation of molecules makes them less stable |
| Glycolysis gives a small net gain of ATP without the use of oxygen |
| In aerobic respiration pyruvate is decarboxylated and oxidized, and converted into acetyl compound. In the link reaction this is attached to coenzyme A to form acetyl coenzyme A. |
| In the Krebs cycle, the oxidation of acetyl groups is coupled to the reduction of hydrogen carriers, liberating carbon dioxide. |
| Energy released by oxidation reactions is carried to the cristae of the mitochondria by reduced NAD and FAD. |
| Transfer of electrons between carriers in the electron transport chain in the membrane of the cristae is coupled to proton pumping. |
| In chemiosmosis protons diffuse through ATP synthase to generate ATP. |
| Oxygen is needed to bind with the free protons to maintain the hydrogen gradient, resulting in the formation of water. |
| The structure of the mitochondrion is adapted to the function it performs. |
