Question

The fight-or-flight response in humans prepares the body to fight off or run away from
a potential threat. This response results from a series of nerve and chemical signals that
direct how cells function. This, in turn, determines the actions of organs in these situations.
Some of the changes experienced by the individuals as part of this response include:
increased pulse rate
increased blood glucose levels
increased breathing rate

Select one of the listed changes experienced by the individual and write it on the line below.
Explain how the change you chose allows the individual to effectively respond to a threat.

Answer 1

When there is an increase in blood glucose levels, your body becomes energized, allowing an individual to be alert and respond quickly to a potential threat. (Glucose is another name for sugar, and this is why people become hyper after eating a lot of sweets)

Answer 2

Increased blood glucose levels. This change can for example help an individual to be able to perform more physical feats over a certain time period as he will have more energy for his muscles; imaging being able to run much faster due to the increased amount of glucose in your body.
