A. Energy producing agents
B. Food storage materials
C. Neurotransmitters
D. Energy storing substances

Answer 1

The adrenaline and noradrenaline are hormones that are released by sympathetic postganglionic neurons to transmit signals. In addition, they are released when the body is under a stressed condition.

Step by step answer: Adrenaline and noradrenaline are two necessary hormones for our well-being. They are released during emergency situations.
In Option A, energy producing agents are mentioned. These hormones are very essential for energy production. The two main hormones to produce energy are thyroxine and cortisol in human beings.

In Option C, neurotransmitters are mentioned. Neurotransmitters are the chemical compounds used to transmit the nerve impulse across the synapse. Tyrosine act as a building block for the synthesis of neurotransmitters such as adrenaline, noradrenaline, and dopamine.
In Option D, energy storing substances are mentioned. These hormones are responsible for energy storage. Insulin and estrogen are the main hormones used for the storage of energy.
Hence, Option C is the correct answer, i.e., Adrenaline and noradrenaline are hormones that act as neurotransmitters in our body.

Note: The adrenaline and noradrenaline are known as stress hormones due to their nature of responding against stress. They are also named as epinephrine and norepinephrine respectively. They regulate and respond to different changes in our bodies.
