Photosynthesis and Cellular Respiration
Term | Definition |
---|---|
TROPHIC LEVEL | each step in a food chain or a food web |
ENERGY | ability to work; it can not be created or destroyed, only transferred |
THERMODYNAMICS | study of the flow and transformation of energy in the universe |
METABOLISM | all of the chemical reactions that occur within an organism |
PHOTOSYNTHESIS | two-phase anabolic pathway in which the Sun's light energy is converted to chemical energy for use by the cell |
CELLULAR RESPIRATION | catabolic pathway in which organic molecules are broken down to release energy for use by the cell |
ADENOSINE TRIPHOSPHATE (ATP) | energy-carrying biological molecule, which, when broken down, drives cellular activities |
CARBOHYDRATE | an organic compound containing only carbon, hydrogen and oxygen, usually in a ratio of 1:2:1 |
THYLAKOID | in chloroplasts, one of the stacked, flattened, pigment-containing membranes in which light-dependent reactions occur |
