photosynthesis and cellular respiration
| Question | Answer |
|---|---|
| one of the principal chemical compounds that living things use to store and release energy | ATP |
| process that requires oxygen | aerobic |
| process that does not require oxygen | anaerobic |
| organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer | autotroph |
| term used by scientists to measure the energy stored in foods | Calorie |
| reactions of photosynthesis in which energy from ATP and NADPH is used to build high energy compounds such as sugars | Calvin Cycle |
| process that releases energy by breaking down glucose and other food molecules in the presence of oxygen | cellular respiration |
| principal pigment of plants and other photosynthetic organisms; captures light energy | chlorophyll |
| organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy | chloroplast |
| a series of proteins in which the high-energy electrons from the Krebs cycle are used to convert ADP into ATP | electron transport chain |
| process by which cells release energy in the absence of oxygen | fermentation |
| first step in releasing the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid | glycolysis |
| organism that obtains energy from the foods it consumes; also called a consumer | heterotroph |
| second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactants | Krebs Cycle |
| reactions pf photosynthesis that use energy from light to produce ATP and NADPH | light-dependent reactions |
| process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches | photosynthesis |
| light-collecting units of the chloroplast | photosystem |
| light-absorbing molecule | pigment |
| region outside the Thylakoid membranes in chloroplasts | stroma |
| a stack of thylakoid membranes | granum |
| process of generating ATP by a proton pump | chemiosmosis |
| most abundant protein on the planet | rubisco |
