the body
◉ It is hydrophobic. Answer: Why is fat the tissue with the least
amount of water in it?
◉ Men. Answer: Do men or women have more water in their body?
◉ Because women have more fat. Answer: Why do men have more
water in their body?
◉ Younger. Answer: Do older or younger people have more water in
their body?
◉ Because younger people have more muscle mass. Answer: Why do
younger people have more water in their body than older people?
,◉ Hydrophilic. Answer: Anything that forms polar covalent bonds
are considered to be...
◉ Hydrophobic. Answer: Anything that forms nonpolar covalent
bonds are considered to be...
◉ Amphipathic. Answer: Both hydrophilic and hydrophobic
◉ Cell membrane. Answer: Made of 2 layers of phospholipids
◉ Phospholipid bilayer. Answer: What type of membrane is the cell
membrane?
◉ H+ and OH-. Answer: What does water dissociate into?
◉ Percentage of water that is ionized never changes as long as
temperature and pressure stay the same. Answer: How is
equilibrium maintained in water?
◉ Equilibrium. Answer: Percentage of water that is ionized does not
change while temperature and pressure stays the same
,◉ Kw= [H+]*[OH-]. Answer: Equilibrium constant of water
◉ 10^-14. Answer: What does Kw equal?
◉ 10^-7 M. Answer: What is [H+] if pH is 7?
◉ 10^-7 M. Answer: What is [OH-] if pH is 7?
◉ 10^-2 M. Answer: What is [H+] if pH is 2?
◉ 10^-12 M. Answer: What is [OH-] if pH is 2?
◉ pH= -log([H+]). Answer: pH equation from concentration of H+
◉ pH is 8 (basic). Answer: What is pH if [H+] is 10^-8?
◉ Forms weak acids and weak bases. Answer: What happens when
biomolecules ionize in water?
◉ One more H, one more positive charge. Answer: Conjugate acid
◉ One less H, one less positive charge. Answer: Conjugate base
, ◉ Conjugate acid. Answer: One more H, one more positive charge
◉ Conjugate base. Answer: One less H, one less positive charge
◉ H2CO3. Answer: Conjugate acid of HCO3-
◉ CO3-2. Answer: Conjugate base of HCO3-
◉ Bicarbonate buffer system. Answer: Blood buffer system
◉ Carbonic anhydrase. Answer: Enzyme in bicarbonate buffer
system
◉ pH drops, blood becomes more acidic (CO2 builds up in blood).
Answer: What happens to pH of the blood with uncontrolled
asthma?
◉ Buffer. Answer: Resist change in pH
◉ Phosphate buffer system. Answer: Cytoplasm buffer system
