Summary
The following content is included:
C1.3.1: Explain how the energy transformation of light energy to chemical energy is needed for most life processes in ecosystems.
C1.3.2: Describe photosynthesis as the conversion of carbon dioxide to glucose.
C1.3.3: Describe the production of oxygen as a by-product of photosynthesis.
C1.3.4: Describe the process of chromatography for separating pigments and the use of Rf values to identify pigments.
C1.3.5: Describe and explain the absorption of different wavelengths of light by photosynthetic pigments.
C1.3.6: Compare absorption and action spectra
C1.3.7: Determine through investigation the effects of limiting factors on the rate of photosynthesis.
C1.3.8: Describe carbon dioxide enrichment experiments as a means of predicting future rates of photosynthesis and plant growth.
C1.3.9: Describe photosystems as arrays of pigments within membranes of photosynthetic organisms that generate and emit excited electrons.
C1.3.10: Explain the advantage that an array of pigments in a photosystem has over individual pigment molecules.
C1.3.11: Describe the photolysis of water in terms of a means of replacing lost electrons in photosystem II and the production of oxygen as a waste product.
C1.3.12: Describe the production of ATP by chemiosmosis through both cyclic and non-cyclic photophosphorylation.
C1.3.13: Describe the reduction of NADP by photosystem I.
C1.3.14: Explain the importance of the thylakoids as the site of photolysis, chemiosmosis and reduction of NADP.
C1.3.15: Describe carbon fixation by Rubisco and the significance of Rubisco as an enzyme.
C1.3.16: Describe the process of generating triose phosphate using ATP and reduced NADP.
C1.3.17: Describe the regeneration of RuBP and the completion of the Calvin Cycle using ATP.
C1.3.18: Describe the production of a variety of carbon compounds from photosynthesis.
C1.3.19: Explain the link between the light-dependent and light-independent reactions and how the light-independent reactions cannot continue in the absence of light.
