Chapter 6 Biology Photosynthesis
Terms in this set (21)
organisms that use energy from sunlight or from chemical bonds in inorganic substances to make organic compounds.
prosess of converting light energy from the sun into chemical energy in the form or organic compounds, primlarily carbohydrates.
animals and other organisms that must get energy from food instead of directly from sunlight or inorganic substances.
light energy (absorbed from the sun) is converted to chemical energy, which is temporarily stored in ATP and the energy carrier molecule NADPH.
organic compounds are formed using CO2 and the chemical energy stored in ATP and NADPH.
organelles found in plant and algae cells where photosynthesis occurs.
a membrane system found within chloroplast that contains the componets for photosynthesis.
a stack of thylakoids in a chloroplast
in plants, the solution that surrounds the thylakoids in chlorplast
compounds that absorb light.
a green pigment that is present in most plant cells, that gives plants their characteristics green color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates.
a class of pigments that are present in the thylakoid membrane of plants and that aid in photosynthesis.
in the thylakoid membranes of choloplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions of photosynthesis.
primary elcetron acceptor
the acceptor of the elcetrons lost from chlorophyll a.
electron transport chain
a series of molecules, found in the iner membranes of mitochondria and chlorplasts, through which electrons pass in a process that causes protons to build up on one side of the membrane.
in chloroplasts and mitochondria, a process in which the movement of protons down their concentration gradient across a membrane is coupled to the synthesis of ATP.
a series of enzyme-assisted chemical reactions that produces a three-carbon sugar.
the synthesis of organic compounds from carbon dioxide, such as in photosynthesis.
one of many openings in a leaf or a stem of a plant that enables gas exchange to occur.
a carbon-fixing process in which carbon dioxide is bound to a compound to form a four-carbon intermediate.
a water-conserving, carbon fixing process; CAM plants take in carbon at night and fix it into various organic compunds and release it during the day.
