Worksheet: Adrenaline

In this worksheet, we will practice describing the effect adrenaline has on the body, and the importance of the 'flight or fight' response.

Q1:

Complete the statement to describe the effect of adrenaline on the liver:

Adrenaline stimulates the conversion of in the liver into so the rate of cellular respiration can increase.

  • Aglycogen, sucrose
  • Bglucose, sucrose
  • Cglycogen, glucose
  • Dglucose, glycogen
  • Eglucagon, glucose

Q2:

  • AIncreases, Constrict, Increases
  • BDecreases, Dilate, Increases
  • CDecreases, Dilate, Decreases
  • DIncreases, Constrict, Decreases
  • EIncreases, Dilate, Decreases

Q3:

Which of the following correctly links adrenaline and breathing rate?

  • AAs the amount of adrenaline released increases, breathing rate increases.
  • BAs the amount of adrenaline released increases, breathing rate decreases.
  • CAs the amount of adrenaline released increases, breathing rate remains constant.

Q4:

Fill in the blank using “increase” or “decrease”: A release of adrenaline will the heart rate.

  • Aincrease
  • Bdecrease

Q5:

How does an increase in adrenaline affect the blood vessels supplying the digestive system?

  • AAn increase in adrenaline widens these blood vessels.
  • BAn increase in adrenaline narrows these blood vessels.
  • CAn increase in adrenaline has no effect on these blood vessels.

Q6:

Which endocrine gland produces and releases adrenaline in the human body?

  • APancreas
  • BThyroid
  • CPineal gland
  • DOvaries
  • EAdrenal

Q7:

Which of the following correctly links adrenaline and the rate of cellular respiration?

  • AAs adrenaline in the body increases, the rate of cellular respiration decreases.
  • BAs adrenaline in the body increases, the rate of cellular respiration increases.
  • CThere is no obvious correlation between the amount of adrenaline released and the rate of cellular respiration.

Q8:

How does an increase in adrenaline affect the blood vessels supplying skeletal muscles?

  • AAn increase in adrenaline widens these blood vessels.
  • BAn increase in adrenaline narrows these blood vessels.
  • CAn increase in adrenaline has no effect on these blood vessels.

  • DD
  • EC

Q11:

Why does a release of adrenaline increase the blood flow to muscles?

  • ATo encourage muscle cell division and replication
  • BTo increase heat transfer from the blood to muscle cells
  • CTo deliver more oxygen and glucose to muscle cells for cellular respiration
  • DTo deliver more oxygen and water to muscle cells for cellular respiration

Q12:

Why is it important that the release of adrenaline increases the rate of cellular respiration?

  • ATo increase blood oxygen concentration
  • BTo provide more energy for digestion to take place
  • CTo ensure the fast removal of waste products
  • DTo provide more energy for the fight or flight response
