awarded the Noble Prize for his discovery that..?
Our body utilizes Carbonic acid and bicarbonate anion to buffer against PH. - answer ✔✔-How does our
body maintain a controlled PH level of 7.2-7.6?
These relatively weak bonds helot provide the structure and shape necessary for proteins and DNA
molecules- by stabilizing their 3-D structure. - answer ✔✔-Why are Hydrogen bonds and Van de Waals
interactions necessary for cells?
, -Membrane

-Micelle - answer ✔✔-What kinds of structures will phospholipids form in?
spontaneous, exergonic - answer ✔✔-A chemical reaction where change in free energy will be less than
0?
tend to become more dispersed over time - answer ✔✔-The 2nd law of thermodynamics suggest the
energy in a system will...
Denaturation - answer ✔✔-If protein is subject to changes in temp, PH, or exposure to chemicals, this
may result in?
Hydrogen bonds - answer ✔✔-what type of chem bond is important for stabilizing alpha-helix or Beta
sheets between backbone amino acids in close proximity?
Large, because the substitution of 2 chemically different amino acids could cause major changes. -
answer ✔✔-Would substitution of alanine for serine have a small or large effect on protein structure?
RNA - answer ✔✔-Single stranded polymer of nucleotides that is involved in protein synthesis
Amino Acids - answer ✔✔-Monomers that make up proteins
Buffer - answer ✔✔-Main mechanism by which our blood maintains a healthy PH?
RNA - answer ✔✔-If a ribose is present in structure it is?
