Answer:
The correct answer would be calcium ion and cAMP.
Secondary messengers refers to the intracellular signaling molecules which pass the signals from the receptors located on the surface of the cell to the target molecule present within the cell.
The secondary messengers can be classified into three major class:
- Cyclic nucleotide for example cAMP (cyclic adenosine monophosphate), cGMP (cyclic guanosine monophosphate)
- DAG (diacylglycerol) and IP₃ (inositol triphosphate)
- Calcium ions (Ca⁺⁺)
Hence, from the given options, calcium ion and cAMP would make the correct choice.
Brain stem is the part of the human brain that houses the most primitive functions such as the control of heart rate, respiration, and blood pressure.
<h3>What is brain stem?</h3>
It is a part of the brain that is located between the rest of the brain and the spinal cord.
It is responsible for carrying out the most basic nervous system tasks for our survival, such as the regulation and maintenance of the heart rate and the automatic control of respiration.
Therefore, we can conclude that the brain stem is the part of the human brain that houses the most primitive functions such as the control of heart rate, respiration, and blood pressure.
