Marking points
- 1 Gives increased heart rate/blood flow as one effect.
- 2 Gives increased breathing rate as one effect.
- 3 Gives increased oxygen delivery as one effect.
- 4 Gives increased glucose delivery as one effect.
- 5 Gives increased respiration/metabolism or energy release as one effect.
- 6 Gives increased sweating as one effect.
- 7 Gives pupil dilation as one effect.
- 8 Gives an accepted redistribution of blood flow as one effect.
- 9 Gives raised blood glucose/glycogen conversion as one effect.
- 10 Gives increased blood pressure as one effect.
- 11 Gives slowed digestion as one effect.
Full-mark answer
1. Adrenaline increases heart rate. 2. It increases breathing rate, helping deliver more oxygen for respiration.
Why this answer loses marks
Adrenaline gives the body energy.
This is vague and suggests energy is made; name two measurable body changes caused by adrenaline.
