Human Biology (Concepts and Current Issues) Final
questions with well verified answers
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
