Answer 1

Answer: (A), (C)

glucose

Adrenline is a hormone, which prepares the body to meet any emergency situation, for "fight" i.e to face danger or for "flight" to run away from it. So it increases the heartbeat to pump more blood. As the blood moves, it carries more glucose to other parts of the body. This glucose is used by the cells to produce more energy. (The final dash to win a race is under the influence of adrenaline.)
