BIOL 101 1nd Edition Lecture 10 Outline of Last Lecture I Glycolysis a visual II Pyruvate Oxidation a visual III Citric Acid Cycle a visual IV Oxidative Phosphorylation a visual Outline of Current Lecture I Photosynthesis a Light Reactions b Calvin Cycle c How does it produce energy Current Lecture Photosynthesis Class Discussion How are trees carbon sinks Relate this to photosynthesis They take in CO2 to make glucose which is used for cellular respiration Also if most of the weight comes from air then a lot is due to CO2 Are they permanent sinks for carbon Why or why not No because eventually they die and decompose How does a plant make its mass Most of a plants mass comes from carbon dioxide through photosynthesis which builds sugar which makes macromolecules that are used during cellular respiration LIGHT RXNS first round of reactions Inputs H20 Light NADP ADP Outputs O2 NADPH ATP CALVIN occurs after Inputs CO2 NADPH ATP Outputs Sugar ADP NADP 1 Describe what happens to electrons once they are on the move They get carried down the electron transport chain to NADP 2 How does the plant get more electrons as they get used up by this process These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute They take in more water from the environment 3 What do electrons have to do with making ATP and NADPH The energy released from the electron transport chain allows the hydrogen ions to be pumped across the membranes which produces a lot of ATP
