Question

Question1- ATP is commonly referred to as the biological "free energy currency." Select which properties of ATP make it a good energy currency: (Choose all that apply)

B. its hydrolysis is highly exergonic

C. it participates in enzyme-catalyzed phosphoryl transfer reactions

D. it is very reactive

E. it can be used to provide energy for reactions that would otherwise be thermodynamically unfavorable

A. it has high-energy bonds

Question2- From the following hydropathy plot, what can you deduce about the properties of this protein? (choose all that apply)

B. It is likely an integral membrane protein

C. It is amphipathic, and will likely interact with the membrane through its hydrophobic regions

D. It appears to have several membrane spanning regions

E. It likely forms a pore in the membrane

A. It is likely to be covalently modified with lipids in the hydrophobic regions, and be associated with the membrane
