    Introduction: Heart Rate is defined as the amount of times a person’s heart beats in one minute. A resting heart rate is the person’s heart rate prior to any activity or exercise. As activity increases‚ the heart rate will increase in speed. An increased heart rate is essential as it replaces oxygen in the muscles that is used during said activity and gets rid of excess carbon dioxide through the blood stream. Blood pressure is the force of the blood pushing on the walls of the veins and arteries

    neurogenic hearts. The myocardial cells need neural input from the cardiac ganglion to be able to beat whereas the myogenic hearts of vertebrates will beat without neural input. The neural input sets the resting heart rate and contractile force of the neurogenic heart. The heart rate of the neurogenic and myogenic hearts is regulated by neurotransmitters. Hearts in vertebrates are excited by epinephrine and serotonin although with varied effects and inhibited by acetylcholine. Invertebrates’ heart rates

    undergoing a permanent change themselves. These proteins are able to do this by lowering the activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed reaction is reduced or can be stopped if the temperature becomes too high. This is due to the fact that enzymes become denatured at high temperatures. Denaturation occurs when the shape of an enzyme is
