1) why are proteins more efficient as long term energy storage for living organisms that fats and sugars?

2) which one is correct? the animal cell membrane consists of: A-proteins & nucleic acids B-lipids & nucleic acids C- lipids & proteins D-proteins & carbohydrates

3) T/F ions and solvents diffuse through animal cell membranes faster than larger organic molecules.

4) which ones correct- proteins are important for a cell's A-structure B- growth C- chemistry D-all of the above E- none of the above

4) changing the amino acid within a protein could change what about the protein? primary structure/overall shape/ its functions/ all of the above

5)microscopic movement characterized by a smooth, gliding motion is: motile movment/cilia/flagellates/seen in protists/all of the above

6)an alteration or destruction of a protein is: its primary structure/a secondary structure/ denaturation/hydrolysis/none of the above

7) examples of large, complex molecules formed by joining together many smaller molecules include: proteins and amino acids/carbohydrates and monosaccharides/ DNA and proteins/ mitochondria and vacuoles

8)which combination of particle and charge is correct? proton: +charged/electron: +charged/ neutron:- charged/ electron: no charge

9)when 2 atoms are combined to form a molecule: negative ions formed/one atom transfers electrons to the other/each atom is attracted to several others around it/ electrons are shares to fill the outer shell of both atoms.

thank you!!!!:)
