WebThe central nervous system regulates reaction time. It comprises approximately 100 billion nerve cells (or neurons) that receive sensory input through sight , sound , smell, touch , and taste sensor signals. These signals are sent to the brain, where they are interpreted and converted into physical and mental responses. WebOnce all of the substrate is bound, the reaction will no longer speed up, since there will be nothing for additional enzymes to bind to. Substrate concentration: Increasing substrate concentration also increases the rate of reaction to a certain point.
