photosynthesis an overview
Term | definition |
---|---|
Light dependent reactions | Reactions in photosynthesis that require light and light absorbing pigments. |
Light independent reactions | Reactions in photosynthesis in which carbon dioxide and energy carrying molecules are used to produce high energy sugars. |
NADP+ | Carrier molecule that transports high energy electrons. |
pigment | Light absorbing molecule. |
Stroma | Fluid portion of the chloroplast that surrounds the thylakoid membrane. |
Thylakoid | Photosynthesis membrane sac found inside chloroplasts. |
ATP synthase | Enzyme that converts ADP and a phosphate group to ATP. |
Calvin cycle | Another name for the light independent reactions in which carbohydrates are produced. |
Electron transport chain | Series of electron carrier proteins that transport high energy electrons during the process of making ATP. |
Photosystem | Cluster of chlorophyll and proteins in the thylakoids essential to the light dependent reactions. |
Adenosine triphosphate (ATP) | Compound that cells use to store and release energy. |
Autotroph | A living thing that captures energy from sunlight or chemicals to make its own food. |
Heterotroph | A living thing that gets its food by consuming other living things. |
Photosynthesis | Process by which autotrophs use sunlight, water, and carbon dioxide to produce carbohydrates and oxygen. |
Chlorophyll | chlorophyll gives plants their green color. |
