Scientists want to examine the effects of a coal-burning power plant on the pH of a lake that is downwind of the power plant. They take samples from a lake that is not downwind of the power plant to serve as a control. However, they did not realize that the lake they chose as a control group was a geothermal hot spring with acidic water. What best describes how their choice of control group could affect the results of their experiment?

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.
