Hint: Insulin is a peptide hormone that is usually helped in production of Beta cells of pancreatic islets These are considered as main anabolic hormones of the body. adrenaline is also known as epinephrine hormone it is usually produced in adrenal gland and by small number of neurons in medulla oblongata

Complete answer:
Adrenaline usually helps in increasing the heart rate, increasing the blood pressure, it also helps in expanding air passage of lungs, expanding the Pupil in the eye, distribution of blood to the muscles and altering the body's metabolism. Insulin regulates the blood sugar level after we eat carbohydrates, break them down into glucose and distributes the glucose in the entire blood stream.
Role of insulin:
1. Insulin is a key hormone regulating glucose breakdown
2. Its major target tissues are the skeletal muscle, the liver, and the adipose tissue.
3. The cellular level, lipid and glycogen metabolism, protein synthesis, insulin activates glucose and amino acids transport and transcription of specific genes
Role of adrenaline
1. It triggers the body's fight-or-flight response.
2. This reaction causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee.
 The target organ of both adrenaline and insulin is liver

Note: Target organs or target cells are organs or Cell whose hormones show their effect. calcium plays a significant role in the inhibition of insulin release by low concentrations of adrenaline. So these two work in anti-mode. Increase in one leads to decrease in another.
