Transcription

1 What cellular structure carries out photosynthesis? Label it s parts Chloroplast double membrane grana thylakoid membrane with chlorophyll stroma What cellular structure carries out respiration? Mitochondrian double membrane cristae infoldings fluid matrix What is this molecule? Identify its parts (A-D) This is an ATP molecule. A = Adenine, B = ribose sugar, C & D = phosphates What role does it play? What breaks off, where, and what then forms? It s role is a usable form of ENERGY for the cell Phosphate breaks off releasing energy + P + ADP Formula for Photosynthesis Identify the reactants and products 6CO 2 + 6H 2 O + Energy C 6 H 12 O 6 + 6O 2 reactants products Why does a plant do this? to make sugar (carbohydrates) for itself - autotroph ATP Formula for Respiration Identify the reactants and products C 6 H 12 O 6 + 6O 2 reactants 6CO 2 + 6H 2 O + Energy products Why do we breath? to make ATP (energy) for our cells

2 Distinguish btw Light Dependent Rxn & Light-Independent Rxn Label the diagram Light Dependent Rxn Light water CO 2 Light-Independent thylakoid ATP NADPH oxygen Calvin Cycle Carbohydrate Where does the light-dependent reaction take place? Where does the light-independent reaction take place? Why don t they take place in the same location? What pigment is necessary for the light depend rxn? Reactants & products for Light Dependent Rxn? Reactants & products for Light Independent Rxn? What organelle does this represent? What process? Label this Splitting glucose =? What molecule is made from the splitting of glucose 2 types of anaerobic fermentation How much ATP is made there What gas is necessary for aerobic respiration? Kreb cycle =? ATP (#) ETC =? ATP (#) What is aerobic respiration? - Where does it occur? - How much ATP is made? - What else is given off in cellular respiration? What is anaerobic respiration? - What s another name for this kind of respiration? - Where does it take place? - How much ATP is made? - What are the two types of Fermentation? - Where do these occur? What are yeast? - Are they prokaryotic or eukaryotic? - Can they carry out aerobic respiration, anaerobic respiration, or both - In terms of energy, what would be best for them to carry out? Aerobic or Anaerobic respiration and why? In the thylakoid membranes of the grana in chloroplast In the stroma (fluid) surrounding the grana. Only Light-Dep. needs the chlorophyll for its rxn Chlorophyll (which is in the thylakoid membranes) light + Water oxygen + ATP + NADPH CO 2 + ATP + NADPH carbohydrate Mitochondrian Cellular Respiration glycolysis 2 pyruvate molecules alcoholic & lactic acid anaerobic = 2 ATP Oxygen Kreb s cycle = 2 ATP ETC = 36 ATP!! Cellular respiration that occurs in the presence of O 2 - in the mitochondrion of eukaryotic cells ATP (a lot) - CO 2 and H 2 O (along with ATP) Cellular respiration in the absence of O 2 - Fermentation - in the cytoplasm of prokaryotic/eukaryotic cells - 2 ATP is made - Alcoholic Fermentation & Lactic Acid Ferment. - In Bacteria and Yeast & in Muscles Yeast are single-celled organisms - Eukaryotic - Both aerobic AND anaerobic (they have mitochondria and will use it if oxygen is present) - Aerobic respiration because they can make as much as 38 ATP whereas with anaerobic respiration they can only make 2 ATP

3 What is this? What is this? Light-Dependent reaction Takes place in the thylakoid membranes in chloroplast It requires chlorophyll to absorb the light Structures: chloroplast, grana, thylakoid membranes Reactants: light & water Products: oxygen + ATP + NADPH Photosystem II then I (to make the latter 2 products) Light-Independent reaction Takes place in the stroma (fluid) since it does not require light, it doesn t have to occur in the thylakoid membranes where chlorophyll is Chloroplasts involved Reactants: CO 2 + ATP + NADPH (latter 2 from light-dep) Products: carbohydrates (and recycles ADP + NADP + ) No photosystems: photo = light, this is the light-indep Reactions. How does CO 2 and O 2 Cycle? Plants take in CO 2 and release O 2 from water. Animals take in O 2 and release CO 2 and water What can be said about plants ability? Plants can take H 2 O (a liquid) and CO 2 a gas and with the energy from the sun, They can make carbohydrates, lipids, protein, and nucleic acids, put them together in cells, and ultimately make LIFE!

What is this Photosystem I or II? What is happening? Structures are involved? When does it occur? Photosystem II (in thlakoid membrane using protein) Water is being split: H + separated 2e - go to ETC Oxygen released Occurs during the Light-dependent rxn. Thus called Photosystem What is this Photosystem I or II? What is happening? Structures are involved? When does it occur? Photosystem I (in thlakoid membrane using protein) Making high energy Molecules: H + is bonded to NADP + along with 2e - to form NADPH And ATP is made to run The Calvin Cycle & make
