Here are the matching Unit 5 keywords and their definitions:
- ADP - a. adenosine di-phosphate; a lower energy, intermediate molecule used to convert to ATP by adding a third phosphate group
- ATP - b. adenosine tri-phosphate: a molecule that carries energy inside cells and is the energy currency of a cell; a product of the light-dependent reactions of photosynthesis
- ATP synthase - c. a protein that creates ATP from ADP during photosynthesis
- Chlorophyll - d. green pigment that captures the energy from the sun
- Chloroplast - e. organelle in a green plant cell that conducts photosynthesis
- Electron transport chain - f. system by which high-energy electrons are moved to photosystem I and hydrogen ions are pumped into the inside of the thylakoid during photosynthesis
- Light-dependent reactions - g. a series of reactions that take the light energy that is captured by the chlorophyll and convert it into chemical energy in the form of NADPH and ATP; consists of photosystem II, the electron transport chain photosystem I and hydrogen ion movement and formation of ATP
- Light-independent reactions (Calvin cycle) - h. a series of reactions that do not require the presence of light energy and take the carbon from carbon dioxide and convert it to carbohydrates (glucose), amino acids, and other compounds
- NADP+ - i. nicotinamide adenine dinucleotide phosphate; an electron carrier molecule that accepts two high-energy electrons and one hydrogen ion to become NADPH
- NADPH - j. nicotinamide adenine dinucleotide phosphate hydrogen; a product of the light-dependent reactions of photosynthesis used to power some of the reactions in the light-independent stage of photosynthesis
- Photosynthesis - k. process that transforms light energy into stored chemical energy
- Photosystem I - l. protein complex where the transfer of hydrogen ions to NADP+ to make NADPH occurs during photosynthesis
- Photosystem II - m. protein complex where light is absorbed, water is split, hydrogen ions are created, and oxygen is released during photosynthesis
- Stroma - n. fluid-filled space that surrounds the stacks of thylakoids inside the chloroplast, within which the light-independent reactions of photosynthesis occur
- Thylakoid - o. sack-like structure surrounded by a membrane inside chloroplasts where the light-dependent reactions of photosynthesis occur
