Polymer
large molecules formed when many small molecules band together
Organic Compounds
any member of a large class of chemical compounds
chemical reactions
process that always results in the interconversion of chemical substances
proteins
large complex polymers composed of carbon hydrogen oxygen nitrogen and sometimes sulfur
electron transport chain
uses an electron carriers such as NADP and FADH2 that make ATP
polarity
when atoms in a covalent bond don't share the electrons equally
condensation
the small molecules that are bonded together to make a polymer have an -H and an -OH groups that can be removed to make a H2O molecules.
ion
atoms or groups of atoms that gain or lose electron
enzymes
type of protein found in all living things
acids
any substances that forms hydrogen ions
bases
any substances that forms hydroixide ions in H2O and has a pH of above 7
isotopes
atoms of the same elements that have differences number of nuetrons
lipids
organic compounds made of mostly of carbon hydrogen with small amounts oxygen
saturated
don't have a double bond
unsaturated
include a double bond
carbs
biomolecule composed of carbon hydrogen and oxygen with a ratio of about two hydrogen and oxygen for every carbon
fats
is a lipid and isn't insoluble in water because their molecules are nonpolar and aren't by H2O molecules
equilibrium
is important in keeping balance in homeostatis
phospholipid bilayer
has a glycerol backbone 2 fatty and chains and a phosphate group
cell size
volume increases faster than surface area and homeostatis is disrupted by large cells.
