development of the stress response. Flashcards
What are hormones?
Metabolic components that support the actions of enzymes
Substances that support the release of infectious toxins in inflammation
Substances produced by the body in response to injury
Chemical messengers found in the body and transported by the blood stream
Substances made in the brain and used in synapses to transfer nerve impulses
Chemical messengers found in the body and transported by the blood stream
Which of the following hormones is immunosuppressant?

Cortisol
Adrenaline
Growth Hormone
Thyroid hormone
Cortisol
What does thyroid hormone do as part of the stress response?
Suppress cell growth.
Causes constriction of blood vessels in the digestive system.
Triggers the release of cytokines to increase the white cell count.
Raises the body’s energy production by stimulating glycolysis.
Increases red blood cell production by stimulating erythropoiesis.
Raises the body’s energy production by stimulating glycolysis.

Hamid has been advised to increase the amount of protein in his diet. He wants to know why?
Because cortisol promotes protein synthesis.
Because it counteracts the salt loss caused by cortisol.
Because cortisol production is inhibited by protein.
Because cortisol production leads to gluconeogenesis.
Because increased protein levels promote production of cortisol.
Because cortisol production leads to gluconeogenesis.
Hamid is currently prescribed fluoxetine, an inhibitor of CYP450 enzymes. What impact could fluoxetine have on other drugs that are also metabolised by the same CYP450 enzyme?
The CYP450 enzyme will work more slowly, leading to a reduced clinical effect of the other drugs.
The CYP450 enzyme will work more quickly, leading to a greater clinical effect of the other drugs.
The CYP450 enzyme will work more slowly, leading to a greater clinical effect of the other drugs.
The CYP450 enzyme will work more quickly, leading to a reduced clinical effect of the other drugs.
The rate of reaction of CYP450 will not change.
The CYP450 enzyme will work more slowly, leading to a greater clinical effect of the other drugs.
