| What are the products of the light reaction that are fed into the Calvin cycle? | ATP and NADPH |
| What is necessary for the Calvin cycle? | CO2, ATP, RuBP, and NADPH |
| What is Rubisco or RuBP carboxylase? | Rubisco or RuBP carboxylase is an enzyme responsible for carbon fixation of RuBP and CO2 to make 3 phosphoglycerate a 3 carbon compound |
| What is carbon fixation? | The incorporation of carbon from CO2 into an organic compound by an autotrophic organism |
| What splits water in the light reaction? | an enzyme |
| What 3 products are produced when water splits? | 2 hydrogens+, 2 electrons, 1/2 O2 |
| What is chemiosmosis? | The production of ATP using energy of hydrogen ion gradients across membranes to phosphorylate ADP; powers most ATP synthesis in cells. |
| What is photophosphorylation? | The process of generating ATP from ADP and phosphate by using light |
| Chlorophyll a in photosystem II absorbs light at _____ nm. | 680 |
| Chlorophyll a in photosystem I absorbs light at ___ nm. | 700 |
| The light dependent stage only takes place in the _______ and is called the _______ _______. | light, light reaction |
| The light independent reaction can occur anytime, if provided with the materials from the l`ight dependent reaction ATP and NADPH and is called the ______ cycle. | Calvin |
| What molecule is the Carbon dioxide acceptor found in the Calvin cycle and is catalyzed by RuBP carboxylase? | RuBP |
| What is a redox reaction? | one compound loses electrons while the other gains electrons |
| What is oxidation? | the loss of electrons or hydrogens OIL |
| If the leaves of a plant are green what color is being reflected? | Green is reflected and blue and red are absorbed |
| What is the least effective color in driving photosynthesis? | green because it reflects green |
| Cyclic electron flow only produces what? | ATP. It will not produce NADPH |
| Non cyclic photophosphorylation uses light energy to produce? | ATP and NADPH |
| In photosynthesis where is the electron transport chain found? | thylakoid membrane of chloroplasts |
| What are grana? | Stacks of thylakoids |
| What can be found in each photosystem? | chlorophyll a found in the reaction center, light gathering antenna complex, mix of chlorophylls and carotenoids |
| The reaction center in which Chlorophyll a in Photosystem I is found is known as P700 why? | chlorophyll a P700 is a pigment that absorbs light best with a wavelength of 700 nm |
| What is a photon? | a quantum or discrete amount of light energy |
| The oxygen atoms that are in oxygen gas produced in photosynthesis came from? | water splitting |
| What is produced in photosystem II as electrons are passed down and electron chain? | ATP |
| In cyclic photophosphorylation _____ is not split and ____ is not produced however ______ is produced. | water is not split, NADPH is not produced and ATP is the only thing produced |
| What powers ATP synthesis in the light reaction? | chemiosmosis |
| Where does the Calvin cycle occur? | stroma |
| What is the original source of energy used by nearly all organisms on earth? | sun |
| What functional group does cellulose have that allows the pigments to attach to the paper in the chromatography lab? | hydroxyl OH- |
| What are the 3 pigments found in Photosystems I and II? | carotenoids, chlorophyll a and chlorophyll b |
| What is the equation for photosynthesis? | 6CO2 + 6H2O + sunlight yields C6H12O6 +602 |
| What is the job of the accessory pigments? | transfer light energy from one molecule to another |
| Organisms that use energy to make organic molecules from inorganic substances are called? | autotrophs |
| Organisms that obtain organic food molecules by eating other organisms or their by products are called? | heterotrophs |
| In the plant chromatography lab which pigment contained no oygen or hydrogen groups and moved the farthest? | carotene |
| In the plant pigment chromatography lab what pigment/pigments contained both oxygen and nitrogen groups? | chlorophyll a and b |
| How do you find the Rf value? | divide the distance the solute or pigment migrated by the distance the solvent migrated |
| What is the process in which carbon dioxide from the atmosphere is converted to carbohydrates? | carbon fixation |
