Which of the following is a possible function of a protein?

enzymes are proteins that speed up chemical reactions in the body and hormones, like insulin, are proteins that regulate the activity of cells or organs. Some proteins transport materials throughout your body, such as hemoglobin, which is the oxygen-transporting protein found in your red blood cells.

The nervous system develops throughout the human body and includes very different elements in their forms and functions. It is divided into two complementary systems, the Peripheral Nervous System (PNS) and the Central Nervous System (CNS).

The SNP includes all the nerve tissue that runs through the body. It has a dual function: to receive information by sensory sensors and transmit them to the CNS, and to activate motor functions controlled by the CNS. It consists of two parts, that somatic, activating the skeletal muscles and that, autonomous, attached to the viscera.

The CNS is the brain and spinal cord. It is the center of information processing.
