Intro Biological molecules

Question 1

Carbon

Answer 1

Ability to form 4 bonds with other atoms and chemicals
can have either single,double or triple bond
held by covalent bonds-C,HO,N,S and F

Question 2

Macromolecules

Answer 2

large biological molecules with repeating sub-units and many functional groups -usually polymers

Question 3

Functional groups

Answer 3

can attach to carbon
dictate function of compound
has specific chemical properties and functions
usually involve transfer(loss or gain)
when covalent bonds are broken, releases energy required in our body.

Question 4

Monomers

Answer 4

join together to form polymers joined together by dehydration synthesis-hydrogen + hydroxyl group removed=H20

Question 5

Polymers

Answer 5

Broken down by hydrolysis-water added=energy(ATP)

Question 6

Water

Answer 6

Joined by covalent bonds-polar
Solvent-move particles during diffusion
Lubricant-joints+tissues, epithelial tissues and is a shock absorber
Regulates body temperature

Question 7

Polar

Answer 7

Partial positive and partial negative charge-hydrophilic

Question 8

Surface Tension

Answer 8

in a liquid attraction of particles reducing surface tension
Elastic tendency of fluid surface
Liquid air interfaces =greater attraction to water molecules then to air.
