During meiosis, which of the following will result in genetic recombination A. chromosomes assorting independently and crossing over occurring
B. genes from different species mixing together
C. gene mutations occurring more frequently than at other times
D. cells dividing only once, resulting in genetically identical cells

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.
