sun

the original source of energy on earth

light

synthesis

to make something

autotrophs

organisms that make all their own organic matter

heterotrophs

organisms that cannot make organic molecules from inorganic ones

cellular respiration

the aerobic harvesting of chemical energy from organic fuel molecules

aerobic

presence of molecular oxygen

anaerobic

lacks presence of molecular oxygen

redox reaction

transfer of electrons and hydrogens from one substance to another

reduction

oxygen gains electrons and hydrogens

oxidation

glucose loses electrons and hydrogens

kreb's cycle

completes the breakdown of sugar all the way to carbon dioxide

glycolosis

a molecule of glucose is split into two molecules of a compound called pyruvic acid, net gain of two ATP, NADH produced for ETC

metabolism

the general term for all the chemical processes that occur in cells

ATP synthase

the turbine-like structures in mitochondrial membrane that are powered by electron transport

electron transport chain

a series of electron carrier molecules that shuttle electrons during the redox reactions that release energy used to make ATP

aerobic respiration equation

C6H12O6+6CO2 _enzymes+ATP_6CO2+6H2O+38 ATP and heat

faculative anaerobe

an organism with the metabolic versatility to harvest food energy by either cellular respiration or fermentation

obligate anaerobe

an organism that is poisoned by oxygen

obligate aerobe

an organism that depends on oxygen and cellular respiration to stay alive

fermentation

the anaerobic harvest of food energy

lactic acid fermentation

the conversion of pyruvate to lactate with no release of carbon dioxide
