membrane bound organelles; plant and animal cells
cell
functional unit of life
transcription
RNA synthesis
translation
protein synthesis
abundant elements
Hydrogen, carbon, oxygen and nitrogen
essential elements
calcium, magnesium, phosphorus, potassium, chlorine, sodium and sulfur
protons
have positive charge, in the nucleus
electrons
have negative charge and located in the energy levels
covalent bonds
bonds with sharing of electrons
ionic bonds
exchanging or transferring of electrons
hydrophobic force
when a nonpolar molecule tries to bond with polar water, waters bond with each other instead and force the nonpolar molecules to bond together
electrostatic attractions
attraction between two oppositely charged molecules; fully and partially charged
hydrogen bonds
attraction of the negatively charged atom and positively charged water molecule
functions of carbohydrates
direct energy source energy storage structural function cell-cell interaction regulate white blood cells enhance white blood cells
direct energy source
glucose
energy storage
glycogen and starch
structural function
chitin, cellulose and chondroitin
cell-cell interaction
glycolipids
regulate white blood cells
lectin
enhance white blood cells
