Adrenaline; AKA: Epinephrine AKA: Norepinephrine all stimulate Alpha 1, Beta 1, and Beta 2 receptors in the body. Stimulating Beta 1 receptors causes less blood flow to non-vital parts of the body thereby giving more blood to important areas such as skeletal muscles, lungs, and brain. Stimulating Beta 1 receptors causes increased heart contraction and the strength of each contraction; this increased blood circulation keeping the blood well oxygenated by the lungs and provides this oxygen to the lungs. Stimulating Beta 2 receptors also causes the airways to enlarge allowing greater airflow to the lungs to further oxygenate the blood. Stimulating Beta 2 receptors also causes arteries to expand to muscles increasing blood to them and causes eyes to dilate to help you see better.
When you bring all this together coupled with the brain just works better on Adrenaline, it just works faster, your responce time is reduced. Muscles have plenty of oxygen and glucose to burn. Your body is ready to preform at its maximum.

How does fatigue affect reaction time?
Fatigue affects reaction time by making it slower.
Why does drinking slow down your reaction time?
Alcohol is a depressant, and affects your brain by depressing its reaction time.
How does ketamine affect driving?
Slows reaction time and affects judgement of distances
What affects the reaction time of a driver?
Using cell phones when driving and using drugs, including alcohol.
Which factor affects the reaction rate by altering the reaction path?
catalyst
Does eye color affect reaction time?
There is no direct scientific evidence to suggest that eye color directly affects reaction time. Reaction time is more likely influenced by factors such as genetics, age, and cognitive abilities. Any correlation between eye color and reaction time would likely be coincidental rather than causation.
How does agitation effect reaction rate?
Agitation affects reaction rate by increasing the amount of collisions the atoms make with one another, therefore speeding up the reaction rate.
What does the rate law tell you about a reaction?
How the concentration of the reactants affects the rate of a reaction
What does the rate law tell you about the reaction?
How the concentration of the reactants affects the rate of a reaction
When smoking cannabis how much does your reaction time slow down by?
I actually speeds it up in theory. Smoking pot increased concentration further more increaseing reaction time. :)_
What affects the speed of reaction in a cell?
Temperature
What is a protein that affects reaction rates?
These are called enzymes.
