1 Algal hysiology I. hotosynthesis I. hotosynthesis in algae II. Characteristics to distinguish algal divisions 1 2 SU : hotosynthetic Unit = Antennae rxn center Light reactions: solar energy is harvested and transferred into the chemical bonds of AT and NADH 3 4 1
2 Chloroplasts Thylakoid flattened vesicles or sacks; thylakoid membrane is where the pigments are Stroma space between inner membrane and thylakoids Granum (pl: grana) stacks of thylakoids yrenoid holds enzyme ribulose bisphospate carboxylase (Rubisco) used in Calvin cycle Calvin Cycle: C fixation from CO 2 to sugar using energy from AT and NADH 5 6 igment Location What light can be used for photosynthesis? 7 8 2
3 What light can be used for photosynthesis? AR = photosynthetically active radiation = 47 nm igments: rimary 1. Chlorophylls green pigments, embedded in thylakoid membrane. Chl a is the main player: used in all algae and land plants. Chl a absorbs light primarily in the blue and farred regions Must also deal with UV light (2832 nm); damage DNA, proteins Bcarotene, aromatic amino acids absorb UVB Reflects green why most plants appear green 9 1 What s wrong with this picture? What s wrong with this picture?
4 Algae have accessory pigments: Allow harvesting of light at middle wavelengths, then channel energy to Chl a Algae have accessory pigments: Allow harvesting of light at middle wavelengths, then channel energy to Chl a SU : hotosynthetic Unit = Antennae rxn center Algal accessory pigments: How we measure photosynthetic rates (primary productivity): Carotenoids brown, yellow, or red pigments. Hydrocarbons with or without an oxygen molecule = carotenes and xanthophylls. 3. hycobilins red or blue pigments. Water soluble. Located on the surface of thylakoids in red algae, associated with proteins to form phycobilisomes Measure Oxygen release With electrodes using O 2 meter or Chemical titration Use Light and Dark Bottles Dark Bottles measure Respiration Light Bottles measure s Rs = Net photosynthesis Light Bottle O 2 Dark Bottle O 2 = Gross photosynthesis measured as O 2 /g/hr
5 How we study photosynthesis: E curve formally known as the s/i curve How we study photosynthesis: The E curve = photosynthesis= oxygen evolved or carbon fixed E= irradiance= measure of the amount of energy falling on a flat surface E curve= useful to compare the physiology of light harvesting pigments Light Intensity Light Intensity How we study photosynthesis: The E curve 1.
