| Question | Answer |
|---|---|
| A nucleotide that occurs in muscle tissue, and is used as a source of energy in cellular reactions, and in the synthesis of nucleic acids. | ATP |
| An organism which requires an external supply of energy in the form of food as it cannot synthesize its own. | heterotroph |
| Any organism that can synthesize its food from inorganic substances, using heat or light as a source of energy. | autotroph |
| The process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts. | photosynthesis |
| Any color in plant or animal cells. | pigment |
| Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria. | chlorophyll |
| a folded membrane within plant chloroplasts from which grana are made, used in photosynthesis. | thylakoid |
| the tissue structure of an organ, etc., that serves to support it. | stroma |
| chemical compound: a coenzyme involved in anabolism, consisting of NAD with an extra phosphate group | NADP+ |
| The reaction taking place in the chloroplast in which the absorption of a photon leads to the formation of ATP and nadph. | light-dependent reactions |
| chemical reactions that convert carbon dioxide and other compounds into glucose. | light-independent reactions |
| Either of two biochemical systems, active in chloroplasts, that are part of photosynthesis. | photosystem |
| A group of compounds that pass electron from one to another via redox reactions coupled with the transfer of proton across a membrane to create a proton gradient that drives ATP synthesis. | electron transport chain |
| An enzyme that catalyzes the formation of ATP from the phosphorylation of ADP with inorganic phosphate, using a form of energy, such as the energy from a proton gradient. | ATP synthase |
| A series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms. | Calvin cycle |
