Chapter 9-ATP and Photosynthesis
| Term | Definition |
|---|---|
| Adenosine Triphosphate (ATP) | source of energy for use and storage at the cellular level |
| heterotroph | organism that acquire energy from other organism |
| autotroph | capture energy from nonliving and converts into living cells can use or can produce their own food |
| photosynthesis | process that converts carbon dioxide and water into oxygen and sugar (the sun is needed) |
| pigment | plants gather the sun's energy with light-absorbing molecules (a substance that produces color in plants and animals) |
| chlorophyll | pigment present in all green plants and a few other organism |
| thylakoid | pouch-like sacs that are bound to a membrane in the chloroplast (part of photosynthesis) |
| stroma | the fluid portion outside of the thylakoids (fluid in chloroplasts) |
| NADP+ | enzyme that Accepts and holds 2 high energy electrons along with a hydrogen ion (H+) |
| light-dependent reactions | use light to break down water to produce oxygen gas, ATP, and NADPH |
| light independent reaction | ATP and NADPH molecules produced in the light-dependent reaction are used to produce high-energy sugars from carbon dioxide ( no light needed for these reactions) |
| photosystem | contain most of the machinery needed to carry out photosynthesis, including clusters of chlorophyll and protein |
| electron transport | series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions (movement of electrons) |
| ATP synthase | it create energy to help with the Calvin cycle and ADP by move H+ ions |
| Calvin Cycle | light-dependent reaction are commonly referred as the Calvin cycle (convert carbon dioxide and hydrogen into glucose) |
