The synthesis of organic compounds from carbon dioxide, such as in photosynthesis
Back
Electron Transport Chain (ETC)
Front
A series of molecules, found in the inner membranes of mitochondria and chloroplasts, through which electrons pass in a process that cause protons to build up on one side of membrane.
Back
Fermentation
Front
The breakdown of carbohydrates by enzymes, bacteria, yeasts, or mild in the absence of oxygen
Back
Anerobic
Front
Describes a process that does not require oxygen.
Back
Carotenoids
Front
a class of pigments that are present mostly in plants and that aid in photosynthesis
Back
Krebs Cycle
Front
a series of biochemical reactions that convert pyruvic acid into carbon dioxide and water; it is the major pathway of oxidation in animal, bacterial, and plant cells, and it releases energy
Back
NADPH
Front
an electron carrier that provides the high-energy electrons needed to make carbon-hydrogen bonds in the third stage of photosynthesis
Back
Calvin Cycle
Front
a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP
Back
Heterotroph
Front
An organism that obtains organic food molecules by eating other organisms or their by products and that cannot synthesize organic compounds from inorganic materials
Back
Chlorophyll
Front
a green pigment that is present in most plant cells, that gives plants their characteristic green color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates
Back
Gycolysis
Front
The anaerobic breakdown of glucose pyruvic acid, which makes a small amount of energy available to cells in the form of ATP
Back
Aerobic
Front
describes a process that requires oxygen
Back
Equation for photosynthesis
Front
6CO2 + 6H2O ------> C6H12O6 + 6O2
Back
equation for cellular respiration
Front
C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy
Back
Autotroph
Front
an organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms
Back
NADH
Front
electron carrier that stores energy used to make ATP
Back
Cellular Respiration
Front
The process by which cells produce energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide
Back
Photosynthesis
Front
the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen
Back
Chemoautotrophs
Front
Organism that make food from chemicals, the go through chemosynthesis
Back
FADH2
Front
electron carrier produced during the Krebs cycle
Back
Thylakoid
Front
a membrane system found within chloroplasts that contains the components for photosynthesis
Back
Pigment
Front
a substance that gives another substance or a mixture its color
