Organic Molecules, Chemistry, and Energy

Question 1

properties of water

Answer 1

adhesion, cohesion, increased specific heat, greater spacing when frozen

Question 2

ions and ionic bonds

Answer 2

when strongly electronegative atoms completely gain electron(s) from the weakly electronegative atom

Question 3

is H+ concentration high or low at low pHs?

Answer 3

H+ concentration is high

Question 4

what is in cells besides water?

Answer 4

ions, minerals, dissolved gasses, carbon-containing compounds (organic molecules)

Question 5

what is an organic molecule?

Answer 5

a carbon containing compound, structure (movement), reactants to make other molecules, energy storage in bonds/energy, control of chemical reactions

Question 6

inorganic carbon

Answer 6

has molecules other than carbon, hydrogen, oxygen, nitrogen, phosphorous, sulfur

Question 7

hydrophilic

Answer 7

polar covalent bonds or ionic (attracted to water)

Question 8

hydrophobic

Answer 8

non polar bonds (not attracted to water)

Question 9

hydrophobic interactions in water

Answer 9

water binds to water instead of being near hydrophobic molecules, maximize water/water interface and minimize water/hydrophobic interface, hydrophobic molecules are pushed together

Question 10

amphipathic

Answer 10

have both hydrophobic and hydrophilic regions

Question 11

cell structure (basic)

Answer 11

intercellular cytoplasm/cytosol, plasma membrane (amphipathic), extracellular cell wall/extracellular matrix

Question 12

1st law of thermodynamics

Answer 12

energy cannot be created or destroyed

Question 13

2nd law of thermodynamics

Answer 13

increase in the sum of entropy of the participating systems

Question 14

potential energy

Answer 14

stored ability to create motion

Question 15

kinetic energy

Answer 15

energy of motion
