Across
- 2. The fluid around the thylakoids in the chrlorplast
- 4. Principal pigment of plants and other photosynthetic organisms; captures light and energy.
- 7. An inorganic compound, with the chemical formula, CO2, composed of two oxygen atoms linked to a single carbon atom by a covalent bond, and essential to many biochemical and biological processes.
- 9. energy-carrying biological molecule, which, when broken down, drives cellular activities. A "fully charged" battery.
- 10. what comes out of a reaction, the product(s)
- 11. Reactions of photosynthesis that use energy from light to produce ATP and NADPH.
- 12. serves as a final electron acceptor of the ETC in cellular respiration, facilitating the movement of electrons down a chain, resulting in the synthesis of ATP (Adenosine triphosphate). Oxygen is released during the light dependent reactions of photosynthesis.
- 14. a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. An example is the chemical reaction that happens with photosynthesis. What you put in is different from what comes out.
- 15. the end result of a reaction. What "comes out" of the reaction. The "output." For example, glucose a product of photosynthesis.
- 18. light-independent reactions during phase two of photosynthesis in which energy is stored in organic molecules as glucose; uses the energy of light-dependent reactions for the manufacturing of carbohydrates and glucose.
- 19. the beginning of a reaction. What you "put in" to a reaction. The "input." For example, water is a reactant for photosynthesis.
- 21. what goes into a reaction, also known as a reactant
- 22. Organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy.
Down
- 1. Also called The Calvin Cycle; uses the electrons from the light-dependent reactions to energize the process, particularly during the conversion of inorganic compounds into organic compounds, such as carbohydrates. They do not require light or energy from the sun to initiate the reaction.
- 3. A molecule that can be converted into ATP through the addition of a phosphate; what ATP becomes when it loses a phosphate
- 5. two-phase anabolic pathway in which the Sun’s light energy is converted to chemical energy for use by the cell; process by which plants use the sun's energy to convert water and carbon dioxide into sugars
- 6. Energy that comes from the sun
- 7. fixation means making something stable. Thus, in biology, carbon fixation involves the addition of carbon dioxide to organic molecules (usually carbohydrates) to prevent it from remaining in the atmosphere in that free state. And in doing so, energy is created. Carbon dioxide fixation is also known as CO2 assimilation.
- 8. Its general chemical formula is C₆H₁₂O₆. Blood glucose, or blood sugar, is the main sugar found in your blood. It is your body's primary source of energy. It comes from the food you eat. Your body breaks down most of that food into glucose and releases it into your bloodstream. a ubiquitous source of energy for every organism in the world and is essential to fuel both aerobic and anaerobic cellular respiration.
- 13. one of the stacks of pigment-containing thylakoids in a plant’s chloroplasts
- 15. light absorbing molecule.
- 16. in chloroplasts, one of the stacked, flattened, pigment-containing membranes in which light-dependent reactions occur; Saclike photosynthetic membrane found in chloroplasts.
- 17. Two hydrogens and one oxygen, H2O. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Photosynthesis converts carbon dioxide and water into oxygen and glucose. Water is a reactant in photosynthesis and a product in cellular respiration.
- 20. Organism that can capture sunlight from energy or chemicals and use it to produce its own food from inorganic compounds; also called producer.
