1. Describe one way you could keep track of energy use and transfer in a biological system. 2. Identify the possible inputs and outputs of mass and energy between the sun and a producer.

3. Identify the possible inputs and outputs of mass and energy between a producer (pansy) and a primary consumer (pansyworm).

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.
