Term
autotroph
Definition
A photosynthetic organism; a producer; an organism that absorbs the sun's energy and converts it into food
Term
photosynthesis
Definition
the process by which the chloroplast abssorbs sunlight and converts it into food = glucose (a carbohydrate)
Term
producer
Definition
Any photosynthetic organism
Term
heterotroph
Definition
Any consumer; any organism that can not do photosynthesis
Term
Consumer
Definition
Any organism that can not do photosynthesis; this organism must eat producers or other consumers
Term
cellular respiration
Definition
process by which organisms take in food molecules (glucose) and convert them to useable cellular energy (ATP) in the mitochondria
Term
kinetic energy
Definition
energy of motion
Term
potential energy
Definition
energy of position or condition
Term
chemical energy
Definition
energy stored in the bonds of molecules, for example, in food
Term
Calorie
Definition
represents the relative amount of energy in a gram of a substance
Term
ATP
Definition
Adenosine triphosphate; a useable form of cellular energy; produced by the mitochondria; transformed from Glucose during cellular respiration
Term
electron transport chain
Definition
a series of reactions that occur inside the chloroplast, in the membrane of the thylakoids, during which time sunlight is converted to Glucose (a carbohydrate)
Term
glycolysis
Definition
the first step of cellular respiration; occurs in the cytoplasm of the cell; takes glucose and breaks it into 2 smaller 3 carbon molecules
Term
Kreb Cycle
Definition
the 2nd part of cellular respiration; occurs in the mitochondria; the 2 smaller 3-Carbon molecules from Glycolysis are converted to ATP
Term
Fermentation
Definition
A type of cellular respiration used by bacteria and other micro-organisms; does not use oxygen; produces less ATP and alcohol as a waste product
Term
anaerobic
Definition
without oxygen
Term
aerobic
Definition
with oxygen
Term
chloroplast
Definition
a cellular organelle found in photosynthetic organisms (producers); the site of photosynthesis
Term
chlorophyll
Definition
a green pigment molecule, found inside chloroplasts, responsible for photosynthesis
Term
thylakoid
Definition
located inside a chloroplast; a special disk-like structure where chlorophyll (the green photosynthetic pigment) is located
Term
stroma
Definition
the liquid inside the chloroplast; the dark reactions of photosynthesis occur here
Term
Calvin Cycle
Definition
the 2nd part of photosynthesis; also known as the dark reactions of photosynthesis
Term
Light reactions
Definition
Part 1 of photosynthesis; requires sunlight; occurs in the thylakoids of the chloroplasts
Term
pigment
Definition
a colored molecule; it absorbs some wavelengths of light and reflects others
