| Question | Answer |
|---|---|
| autotroph | organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer |
| heterotroph | organism that obtains energy from the foods it consumes; also called a consumer |
| adenosine triphosphate (ATP) | one of the principal chemical compounds that living things use to store and release energy |
| photosynthesis | 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 |
| pigment | light-absorbing molecule |
| chlorophyll | principal pigment of plants and other photosynthetic organisms; captures light energy |
| thylakoid | saclike photosynthetic membrane found in chloroplasts |
| photosystem | light-collecting units of the chloroplast |
| stroma | region outside the thylakoid membranes in chloroplasts |
| NADP+ (nicotinamide adenine dinucleotide phosphate) | one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules |
| light-dependent reactions | reactions of photosynthesis that use energy from light to produce ATP and NADPH |
| ATP synthase | large protein that uses energy from H+ ions to bind ADP and a phosphate group together to produce ATP |
| Calvin cycle | reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars |
