C) norepinephrine
D) glucose

During a state of emotional arousal, the adrenal glands release norepinephrine into the bloodstream. This hormone helps to prepare the body for the stressor by increasing heart rate, blood pressure, and respiration. It also increases the release of glucose from the liver to provide energy for the body. Insulin is released by the pancreas to regulate blood sugar levels, while acetylcholine is a neurotransmitter involved in muscle movement and cognitive functions. Glucose is a type of sugar that serves as a primary source of energy for the body.
