ATP
transfers energy from the breakdown of food molecules to cell products
ADP
a lower-energy molecule that can be converted to energy
chemosynthesis
process by which some organisms use chemical energy to make energy storing carbon based molecules
photosynthesis
captures energy form sunlight to make sugars that store chemical energy
chlorophyll
molecule in chloroplasts that absorbs some of the energy in visible light
thylkaloid
membrane bound structure within chloroplasts that contains chlorophyll and other light absorbing pigments used in light dependent reactions of photosynthesis
light dependent reactions
capture energy from sunlight and take place within and across the membrane of a thylkaloid
light independent reactions
use energy from the light dependent reactants to make sugars occur in stroma of chloroplasts
cellular respiration
releases chemical energy from sugars and oxygen carbon based molecules make ATP when oxygen is present
aerobic
needs oxygen to take place
anaerobic
doesn't need oxygen to take place
glycolysis
splits glucose into three carbon molecules and makes two molecules of ATP
krebs cycle
produces molecules that carry energy to the second part of cellular respiration
fermentation
removes electrons from NADH molecules and recycles NAD=molecules for glycolosis
lactic acid
product of fermentation which causes your muscles to burn
autotrophs
organism that obtains its energy from a biotics sources such as sunlight or inorganic molecules
guard cells
one of the pair of cells that controls the opening and closing of a stoma in a plant tissue
muscle fatigue
build up of lactic acid in muscle tissue during anaerobic respiration
alcohol
product of the fermentation in plant cells
gas exchange
diffusion of gases between organisms and its environment
