The goalkeeper will attempt to stop the forward from scoring a goal by preventing the ball from passing the goal line. A New Zealand forward (in white) takes a shot on goal against Cameroon in the 2011 FIFA U-20 World Cup.
32. After aerobic respiration, 38 ATP molecules are produced from the consumption of one glucose molecule (but two of these ATP molecules are consumed by glycolysis). The net gain of the process is then 36 ATP molecules per glucose molecule.
Answer Guide. ATP (adenosine tri-phosphate) can be thought of as the currency of the cell. Most cellular metabolic processes cost a certain amount of ATP in order to happen. Furthermore, during glycolysis and cellular respiration when ATP is produced, ATP must be invested before more ATP can be generated.
