Photosynthesis
Hon. Bio
| Question | Answer |
|---|---|
| Photosynthetic organelle | chloroplast |
| Reaction that is independent of light | Calvin Cycle |
| Photosynthetic Pigment | chlorophyll |
| original source of energy | sunlight |
| stacks of thylakoids | granum |
| gel-like material in chloroplast | stroma |
| Reactants (chemical equation) | 6CO2 + 6H2O |
| Products (chemical equations) | C6H1206 + 6O2 |
| Internal membranes | thylakoids |
| Reaction that is dependent on light | Light (dependant) Reaction |
| sugar products of the calvin cycle | PGAL or GEP |
| energy molecule used in the calvin cycle | ATP |
| starting molecule in the calvin cycle | RuBP |
| Site of the light reaction | thylakoid membrane |
| enzyme needed for the calvin cycle | Rubisco |
| cluster of chlorophyll-captures light E | photosystems |
| pumped from the stroma to the lumen/diffuse back to the stoma | H+ |
| Phospholipid bilayer | thylakoid membrane |
| products of light reaction | ATP & NADPH |
| gas needed for the calvin cycle | carbon dioxide |
| energy from e- are used to pump the ions | H+ |
| calvin cycle occurs here | stroma |
| space inside the thylakoid space | lumen |
| ADP + pi | ATP |
| Photosystem where H2O is split | PS 2 |
| split into e- H+ O2 | H2O |
| NADP + e- + H+ | NADPH |
| Photosystem where the electrons are re-energized | PS 1 |
| proteins that carry e- from PS 2 PS 1 | ETC (electron transport carrier) |
| enzymes produces ATP when H+ diffuses through it | ATP synthase |
| controls the openning and closing of the stoma | guard cell |
| tissue that transports H2O + minerals | xylem |
| proteins inner tissue | lower + upper epidermis |
| tissue transports sugars | phloem |
| pores in the leaf (O2 + CO2 + H20) | stoma/stomata |
| most photosynthesis takes place here | palisade and spongy layer |
| molecules at the end of the calvin cycle | PGAL, ADP + pi,NADP+ |
| this wavelength is reflected | green wavelength |
| transformation of energy | light - electrical - chemical E |
| 1. Photo 2. Synthesis | 1. means light thylakoid 2. means C in the calvin cycle |
| chlorophyll a + b absorbs these wavelengths of light | Red and Blue wavelengths |
| released through the stoma | O2 |
| pigment thats aid in photosynthesis | caretenoids (see color in fall) |
| drops of H+ + e- in the calvin cycle | NADPH (reducing power) |
| pigments being reflected | color of the object |
| molecules at the end of the light reaction | ATP, NADPH, O2 |
| What did Van Helmont do? | • Planted a seed into A pre-measured amount of soil and watered for 5 years • Concluded Mass Came From Water |
| Priestly | • Burned Candle In Bell Jar Until It Went Out • Concluded Plants Released Substance (O2) Necessary For burning. |
| Ingenhousz | -Repeated Priestly's experiment without sunlight • Showed That Priestley’s Results Only Occurred In The Presence Of Sunlight. |
| Mayer | Proposed That Plants can Convert Light Energy Into Chemical Energy |
| Ruben & Camen | Used Isotopes To Determine That The Oxygen Liberated In Photosynthesis Comes From Water |
| Calvin | • First to trace the path that carbon (CO2) takes in forming Glucose • Does NOT require sunlight • Called the "Calvin Cycle" or Light Independent Reaction • Also known as the Dark Reaction |
| Marcus | First to describe the Electron transport Chain |
| What enviorment are C4 plants located? | tropical |
| What enviorment are Cam plants lcoated? | desert |
