Old norse stories tell of a famous viking named egil, who lived around 900 ad. his skull was greatly enlarged and misshapen, and the cranial bones were thickened (6 cm, more than 2 inches, thick). he had headaches from the pressure exerted by enlarged vertebrae on his spinal cord. so much blood was diverted to his bones to support their extensive remodeling that his fingers and toes always felt cold and his heart was damaged through overexertion. what bone disorder did egil probably have?

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.
