9. assume that a dna molecule contains 100 base pairs.
one base pair is (a paired with t) or (c paired with g.)
there are 45 cytosines in this dna molecule. (2 points)
a. how many guanines are there? (hint: what base will guanine bond with? how many of those are there? )
b. how many adenines are there? (hint: the total number of base pairs will equal 100.)

How do high-energy electrons from glycolysis and the krebs cycle contribute to the formation of atp from adp in the electron transport chain? a. high-energy electrons interact with pyruvic acid to create a phosphate bond with adp, forming atp. b. high-energy electrons supply the needed energy to synthesize atp from the lower-energy adp in the electron transport chain. c. high-energy electrons supply a negative charge which causes the citric acid to oxidize, forming a phosphate group to bond with adp. d. high-energy electrons increase the temperature of adp so it easily reacts to form atp.
