A deck containing questions on topic C1.3. Photosynthesis in IB biology HL.
| Front | What does the absorption spectrum show? |
| Back | The percentage of light energy absorbed at the different wavelengths by a certain pigment |
| Front | How are electrons affected in the photosystems? |
| Back | When the photons are absorbed, the electrons in the antenna pigments get excited. When they lose energy, they drop back down and the energy is passed to the next electron. In this way, the energy reaches the reaction centre |
| Front | What are the factors that affect the rate of photosynthesis? |
| Back | 1. Light intensity (graph levels off)2. Temperature (bell curve)3. CO2 concentration (graph levels off) |
