Reaction Rate is the measure of how quickly an organism’s neurons can communicate or react to a type of stimulus. In other words it is how fast an organism’s neurons can send signals to the brain and from the brain.
The anatomy of a classic neuron is rather simple. A classic neuron comprises of a body and a tail. The body has a nucleus with arms protruding outwards, these are called dendrites. Dendrites are the postsynaptic neurons for synaptic communication, they receive neurotransmitters from the presynaptic neurons. A presynaptic neuron is called the axon terminal, it is located at the end of the tail or axon of a classic neuron. The axon terminal has vesicles that exocytose neurotransmitters that transport through synaptic channels and move towards the postsynaptic neuron, this usually is caused by an action potential. The axon, where the axon terminal resides, is a long tail extending from the body of the neuron. The axon is covered by several sheaths called myelin sheaths, these myelin sheaths help insulate the axon and conduct action potential. Within the myelin sheaths are Shwann cells which help produce myelin. This is only a classic neuron, there are many other specific types of neurons within the body, but three main neurons are sensory neurons, motor neurons, and interneurons. Sensory neurons are afferent neurons; neurons that send signals to the brain. These neurons are part of the peripheral nervous system, they sense the internal and external conditions of the organism. Unlike sensory neurons, motor neurons are part of the central nervous system. Motor neurons are efferent neurons, they carry signals from brain to tissues, organs, and organ systems. The only similarity between motor and sensory neurons is they both...

...only used a small amount of cocoa. Further experiments that used a higher concentration of cocoa could show stronger evidence of whether cocoa increase or decreases reaction rate. Also, other than cocoa, sugar should be one variable to continue research because the white chocolate group showed a decrease in reaction rate which could be from the high amounts of sugar in the chocolate.
There are a couple of ways to improve for future experiments. One way to improve the experiment would be to use chocolate with a higher concentration of cocoa, but with the same types and quantities of ingredients in the control. Also, making sure the subjects did not consume any other foods and all had the same physical conditions could help improve the experiment. A last improvement to make would be to use a larger pool of subjects and to have a larger variety of reaction rate tests.

Essay about Rate of Reaction of Dilute Hydrochloric Acid and Sodium Thiosulphate

- Rate of Reaction of Dilute Hydrochloric Acid and Sodium Thiosulphate To investigate the change in rate of reaction between DILUTE HYDROCHLORIC ACID and SODIUM THIOSULPHATE as the concentration varies. PLAN A chemical reaction takes place over a specific period of time i.e. which is the time for the reactants to be formed into the products. If the reactants take a relatively short time to form the products, the reaction is known as a FAST one. The RATE of that particular reaction is high. On the other hand, a reaction which takes a longer time is known as a SLOW reaction, and as a result is known to have a LOW rate of reaction....   [tags: Reaction Rates Chemical Reactions Essays]

Rate of Reaction Essay

- Rate Of Reaction Introduction I will be investigating the rate of reaction, which is the amount of substance taken for the reaction. Often the rate curve is a negative correlation. As we increase the temperature, the time taken for the cross to disappear will decrease. Other Information The most important factors that affect the rate of reaction are: Concentration of the acid Time taken for the cross to disappear Temperature Concentration of Sodium thiosulphate The reaction will not take place unless the particles will collide with each other....   [tags: GCSE Chemistry Coursework Investigation]

Plan for Rate of Reaction for Halogenoalkanes Essay

- Plan for Rate of Reaction for Halogenoalkanes Aim === Aim of the experiment is to find out and compare the rate of displacement of the halide ion and how is varies with respect to the carbon halogen bond. This will occur through a nucleophilic attack. General equation: general formula: R-X +: Nu- ® R-Nu + X- CnH2n+1X (where X is the halogen) Background information halogenoalkanes ====================================== In the reaction of halogenoalkanes bond polarity show us that C-F would be the most reactive then C-CL, C-Br and C-I would be the lest reactive....   [tags: Papers]

Investigate the effects of the concentration of reactants on rate of reaction

- In this experiment I intend to investigate the effects of the concentration of reactants on rate of reaction. Planning In this experiment I intend to investigate the effects of the concentration of reactants on rate of reaction. Specifically I will investigate what effect varying the concentration of hydrochloric acid has when it is reacted with sodium thiosulphate. The details of how a reaction works on a molecular level are described by the collision theory. The collision theory explains the circumstances under which collisions between the particles of the reactants involved in a reaction must collide, in order for a reaction to occur....   [tags: GCSE Chemistry Coursework Investigation]

Rates of Reaction Experiment Essay

- Rates of Reaction Experiment Rate of reaction means the rate of formation of a product/disappearance of a reactant, this is useful because we can time the different concentrations reacting with the acid, and give each of them a rate, based on the formula rate = 1/time. Rate of reaction is what we use to measure how quickly a reaction takes to reach a certain point in the reaction in this case it is when it gets to certain cloudiness. In this investigation, we will need to measure the time of the reaction, so we can make a rate for it, to do this we use the formula, - rate = 1/time * 1000, we use the *1000 so that it is a manageable number to plot on a graph if ne...   [tags: Papers]
