Across
- 1. the reaction-center chlorophyll a molecular dimer associated with photosystem II in plants, algae, and cyanobacteria, and central to oxygenic photosynthesis.
- 4. A colorless, odorless gas. It is needed for animal and plant life.
- 5. a colorless, odorless gas. It is a waste product made by the body.
- 6. copper-containing protein that mediates electron-transfer. It is found in a variety of plants, where it participates in photosynthesis.
- 8. the most important substrate of cell metabolism. It is the carbohydrate fulfilling the task of being the energy transport system of the body.
Down
- 1. an isoprenoid quinone molecule involved in the electron transport chain in the light-dependent reactions of photosynthesis.
- 2. small containing iron and sulfur atoms organized as iron-sulfur cluster.
- 3. A chemical substance, with chemical formula H2O, that is a clear, colorless, odorless, and tasteless liquid that may also occur in various forms such as gas (water vapor) and solid (ice)
- 6. a quantum of radiant energy with a visible wavelength.
- 7. It plays a crucial role in many of the chemical reactions that make up the procedure of the photosynthesis.
