Answer:
What can be noticed about the ligands and their receptor is that the configuration of both coincide, as a key would with its lock, which demonstrates the specificity of a receptor by its ligand.
Explanation:
A <u>ligand</u> corresponds to a molecule considered a signal or a messenger, while the <u>receptor</u> is a protein on the cell surface, with the capacity to accept a ligand.
Ligands and receptors constitute pairs that complement each other, so that <u>each receptor can bind to a specific ligand</u>, similar to what happens with a key and a lock.
Once the ligand-receptor complex is formed, changes occur inside the cell, which define a certain effect.
Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate.
<u><em>Female:</em></u>
*Ovaries - release of oocytes (eggs), estrogen and progesterone.
*Oviducts (fallopian tubes) - where fertilization of the oocyte occurs to form a zygote.
*Uterus - where the zygote develops
*Cervix and vagina - allow for the entry of sperm for fertilization
<u><em>Male:</em></u>
*Testes - Releases testosterone and sperm
*Vas deferens - Passageway for sperm
*Epididymis - allows the sperm to pass from the testes and vas deferens and equips them with semen so they can survive internal fertilization
*Penis - releases sperm into the external environment for fertilization to occur
