<span>The
enzyme name that catalyzes the reaction that converts fibrinogen to fibrin is <span>Thrombin. </span>The thrombin is
an enzyme - type peptidases. It is not part of the blood, but is <span>formed as part of the blood clotting process.</span></span>
Neurons are the building blocks of the nervous system. They are the links so that information could be processed as electrochemical signals. There are three fundamental kinds of neurons in our body:
1. Motor neurons - they carry signals from the central nervous system (CNS) to the body parts such as muscle movement
2. Sensory neurons - they carry signals from other body parts to the CNS
3. Interneurons - interlinking neurons between the brain and the spinal cord
Thus, the correct and complete statement above should be
<span><em>Motor (efferent) neurons carry information </em><em>from </em><em>the brain whereas sensory (afferent) neurons carry information</em><em> to</em><em> the brain.</em></span>
The study of chemical reactions of living this is called biochemistry.
