autotroph
producer, plant capable of synthesizing its own food from simple organic substances; producer
heterotroph
an organism that depends on complex organic substances for nutrition; consumer
ATP
one of the principal chemical compounds that living thing use to store and release energy
ADP
ATP regenerates; as need by using the energy in foods like glucose
photosynthesis
process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches
chloroplast
organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
chlorophyll
green pigment in plants that absorbs light energy used to carry out photosynthesis
pigment
light-absorbing molecule
visible light
(physics) electromagnetic radiation that can produce a visual sensation
thylakoid
a flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
photosystem
a cluster of chlorophyll and other molecules in a thylakoid that help to harvest light energy during photosynthesis
stroma
region outside the thylakoid membranes in chloroplasts
L.D.R.
reaction taking place in the chloroplast in which the absorption of a photon leads to the formation of ATP and NADPH
Calvin cycle
reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars
NADP+
carrier molecules that tranfers high engergy electron from chrrophyll to other molecules
glycolysis
first step in releasing the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid
fermentation
a process in which an agent causes an organic substance to break down into simpler substances
cellular respiration
process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
aerobic
process that requires oxygen
anaerobic
process that does not require oxygen
E.T.C
a series of proteins in which the high-energy electrons from the Krebs cycle are used to convert ADP into ATP.
Joseph Priestly
finds the plant releases oxygen that keeps the candle burning
Melvin Calvin
traces the chemical path that carbon follows to form glucose
Jan Ingenhousz
finds that aquatic plants produce oxygen bubbles in light but NOT in dark. PLants need sunlight to produce oxygen
