Term | Definition |
---|---|
energy | the capacity to do work |
cellular respiration | the process of transferring energy from carbohydrates (or other organic molecules) to ATP |
ATP | supplies the energy needed for many biochemical reactions |
C6H12O6 -> 6CO2 + 6H20 + 36ATP (glucose + oxygen -> carbon dioxide + water + energy) | formula for aerobic respiration |
aerobic respiration | an energy releasing, oxygen dependent metabolic pathway that takes place in the mitochondria of the cell |
anaerobic respiration | produces ATP from carbohydrates without any requirement for oxygen |
alcoholic fermentation | one form of anaerobic respiration, only two molecules of ATP are released per glucose molecule; however, this is sufficient energy to maintain the metabolism of organisms (such as yeast) |
C6H12O6 -> 2CH3CH2OH + 2CO2 + 2ATP (glucose -enzymes-> ethanol + carbon dioxide + energy) | formula for anaerobic respiration |
6CO2 + 12H2O -> C6H12O6 + 6O2 + 6H2O (carbon dioxide + water -light energy/chlorophyll-> glucose + oxygen + water) | formula for photosynthesis |
photosynthetic pigments | involved in the initial capture of light energy |
chlorophylls | photosynthetic pigments which primarily absorb violet, blue, and red wavelengths |
carotenoids | absorb wavelengths of light not absorbed by chlorophyll a; present in plants and some algae |
paper chromatography | allows the pigments to be separated based on their different physical characteristics |
solubility | how well it dissolves in the given solvent |
chromatogram | the final product, showing separate pigments |
