Item EB039002: The reaction between glucose + oxygen to form carbon dioxide + water transfers energy to the reaction between ADP + Pi to form ATP + H2O and the reaction between ATP + H2O to form ADP + Pi transfers energy to allow a person to move.
An energy transfer model shows the direction of energy transfer between two systems. Each box in the model represents a system and the thick arrow between the boxes represents the direction of energy transfer. Each box represents a chemical reaction or process that either gives off or takes in energy. Processes that give off energy are represented with a curved arrow pointing down and processes that take in energy are represented by a curved arrow pointing up.
Which of the following transfer diagrams illustrates how a person gets the energy needed to run?
