Question

Quizplus · Accepted Answer

Endorphins are released during physical exercise and can cause a "runner's high," which is a rush of positive feelings. Option A is incorrect because norepinephrine levels increase during physical exercise. Option B is incorrect because insulin regulates blood sugar levels, not mood. Option D is incorrect because GABA is an inhibitory neurotransmitter, and decreased levels would not cause a rush of positive feelings.
