a. glucose and adrenaline
b. dopamine and serotonin
c. cortisol and insulin
d. adrenaline and melatonin
what chemical released during exercise provides a motivation boost?
a. adrenaline
b. dopamine
c. serotonin
d. endorphins

Explanation:

First Question:

To determine the neurotransmitters improved by exercise for mental health:

• Option a: Glucose is a sugar (not a neurotransmitter), adrenaline is a hormone/neurotransmitter but not paired with glucose for mental health improvement. Eliminate.
• Option b: Dopamine (reward/motivation) and serotonin (mood regulation) are neurotransmitters increased by exercise, improving mental health.
• Option c: Cortisol (stress hormone) and insulin (regulates blood sugar) are not neurotransmitters or paired for mental health from exercise. Eliminate.
• Option d: Melatonin (sleep regulation) is not linked to exercise - related mental health boosts with adrenaline. Eliminate.

To identify the chemical for motivation during exercise:

• Option a: Adrenaline (fight - or - flight) boosts energy but not primarily motivation. Eliminate.
• Option b: Dopamine is associated with reward, motivation, and pleasure. Exercise releases dopamine, enhancing motivation.
• Option c: Serotonin improves mood but is less linked to motivation compared to dopamine. Eliminate.
• Option d: Endorphins reduce pain/stress, not directly boost motivation. Eliminate.

Answer:

b. Dopamine and serotonin
