energy and cells
Stack #220278
| Question | Answer |
|---|---|
| the ability to do work | energy |
| the study of the flow and transformation of energy in the universe | thermodynamics |
| all of the chemical reactions in a cell | metabolism |
| the anabolic pathway in which light energy from the sun is converted into chemical energy for use by the cell | photosynthesis |
| the catabolic pathway in which organic molecules are broken down to release energy for use by the cell | cellular respiration |
| the most important biological molecule that provides chemical energy | adenosine triphosphate |
| flattened saclike membranes that are arranged in stacks | thylakoids |
| stacks that thylakoids form | grana |
| the fluid-filled space that is outside the grana | stroma |
| light-absorbing colored molecules | pigments |
| electron carrier | NADP+ |
| second phase of photosynthesis- energy is stored in organic molecules such as glucose | calvin cycle |
| an enzyme | rubisco |
| the first stage, glycolysis- does not require oxygen | anaerobic process |
| includes the Krebs cycle and electron transport and is an aerobic process | aerobic respiration |
| metabolic processes require oxygen | aerobic |
| glucose is broken down in the cytoplasm | glycolysis |
| the series of reactions in which pyruvate is broken down into carbon dioxide | Krebs cycle |
| occurs in cytoplasm and regenerates the cell's supply of NAD+ while producing small amount ATP | fermentation |
