TermDefinition
ATP an organic molecule that acts as the main energy source for the cell; composed of a nitrogenous base, a sugar, and three phosphate groups.
chemosynthesis the process by which ATP is synthesized by using chemicals as an energy source instead of light
photosynthesis the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen
chlorophyll a green pigment that is present in most plant cells, that give plants their characteristic green color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates.
thylakoid a membrane system found within chloroplasts that contains the components for photosynthesis
light-dependent reactions part of photosynthesis that absorbs energy from sunlight and transfers energy to the light-independent reactions
light-independent reactions part of photosynthesis that uses energy absorbed during the light-dependent reactions to synthesize carbohydrates
Calvin cycle a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP( also called the light-independent reactions)
cellular respiration the process by which cells produce energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide
aerobic process that requires the presences of oxygen to occur
glycolysis the anaerobic breakdown of glucose into pyruvic acid, which makes a small amount of energy available to cells in the form of ATP
Krebs cycle 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
fermentation the breakdown of carbohydrates by enzymes, bacteria, yeast or mold in the absence of oxygen
lactic acid product of fermentation in many types of cells, including human muscle cells
protist an organism that belongs to the kingdom protista
protozoa animal-like protist
pseudopod temporary extension of cytoplasm and plasma membrane that helps protozoa move and feed (literally means "false foot")
cilia short hairlike structures that cover some or all of the cell surface and help the organism swim and capture food
algae photosynthetic microscopic protists, such as algae
slime mold protist with a slimelike amoebiod stage that grows on decaying vegetation and in moist soil
water mold fungus that is either a parasite or decomposer and lives in fresh water or moist soil
