Human Biology Concepts and Current Issues Test Bank Test Bank and
Solutions For Human Biology 17th Edition By Sylvia Mader
Covalent Bond - (ANSWER)an electron sharing bond
strongest chemical bonds in nature
rarely breaks
Ion - (ANSWER)An electrically charged atom of molecule
has shortage or surplus of more than one electron
Ionic Bond - (ANSWER)two oppositely charged ions come together
weaker than covalent
Polar - (ANSWER)molecules such as water that are electrically neutral overall but still have partially
charged regions or poles
Hydrogen Bond - (ANSWER)WEAK attractive force between oppositely charged regions of polar
molecules that contain covalently bonded hydrogen
Keeps DNA together
What is the most essential molecule? - (ANSWER)Water
makes up 60% of our body weight
Solvent - (ANSWER)is a liquid in which other substances dissolve
Solute - (ANSWER)any dissolved substance
Organic molecules - (ANSWER)molecules that contain carbon and other elements held together by
covalent bonds

Dehydration Synthesis - (ANSWER)macromolecules are built within the cell itself
smallest units are simple sugars and the macromolecule is carbohydrate
REMOVES water molecules
Hydrolosis - (ANSWER)macromolecules are broken down
a water molecule is added each time a covalent bond is broken
Monosaccharide - (ANSWER)"one sugar"Ribose, deoxyribose, glucose, fructose, most important in
humans
Oligosacchrides - (ANSWER)Short strings of monosaccharides linked together by dehydration synthesis
(Sucrose)
Polysaccharides - (ANSWER)are a convenient way for cells to stockpile extra energy by locking it in the
bonds of the polysaccharide molecule
Lipids - (ANSWER)do no dissolve in water
triglycerides - (ANSWER)neutral fats. saturated fats, unsaturated fats
stored in adipose (fat) tissue and are an important source of stored energy in our bodies
phospholipids - (ANSWER)modified fats
steroids - (ANSWER)relativly insoluable in water
Protiens - (ANSWER)macromolecule
