[Biology Class Notes] on Difference Between Enzymes and Hormones Pdf

To maintain, control, manage, and direct every physiological and anatomical function of the body, it requires the action of certain chemicals. From digesting the food eaten to helping in deep sleep, these chemicals called hormones and enzymes have a significant part in a human’s day-to-day- life. 

We are about to look at the 2 important categories of these bodily chemicals, namely enzymes and hormones, with examples. We will also understand the difference between hormone and enzyme, along with its features.

Enzymes vs Hormones

Enzymes are a type of catalyst that helps in processing a bodily reaction. This means enzymes do not change in their form or function but instead helps to increase the rate of a particular reaction. Enzymes are produced in the Exocrine glands such as sweat and saliva. Trypsin, amylase, maltase are some of the other examples of enzymes. 

On the other hand, hormones are chemical messengers that trigger the reaction to occur. Hormones are varied in their form, and some of the prominent ones include steroids, amino acids, and even a few protein structures. Body hormones process the pituitary and thyroid glands from the endocrine glands. 

Hormones and enzymes are also present in plants and animals, but the secretion and purpose vary in both. One of the key features that differentiate hormones from enzymes lies in their chemical composition. Some of the other contrasting features in a hormone vs enzyme include the following. 

The Difference Between Enzymes and Hormones

• As stated above, enzymes are biological catalysts, and they do change in their composition. They will help in increasing the pace of a reaction or function. Whereas, hormones are molecules or majorly protein contents that trigger a function to happen inside the body. 

• Enzymes act based on their vitamin compounds and other inorganic prosthetic groups, without which they cannot function. Yet, hormones do not require any prosthetic groups. 

• Puberty (physical maturity in males and females) is the main influencing factor that affects hormones, causing changes and alterations in the person. Yet, enzymes are not linked to age factors and do not change or get affected.

• The reaction time of enzymes is usually quick. But hormones are both slow (lag time) and fast depending on their purpose, target, and composition.

• External factors such as pH levels, temperature, air pressure, activators, substrate concentration, all affect enzymes, and their regulation. But hormones are rigid to these factors and remain constant to changes in the environment. 

Conclusion

The rate of processing and the way a function is controlled are both important. Hormones and enzymes play their roles in the same and are equally significant to the proper development and functioning of the body. From triggering and processing to correctly handling and sending messages for a chemical reaction, enzymes and hormones are critical to human living and existence.
