Cells and Membrane Structure
The topic that I found most relevant to my everyday life is the role of antibiotics in fighting bacteria in the body. I have appreciated the part played by antibiotics in that they target bacterial cells, thereby disabling of killing infectious bacteria that would otherwise be harmful to the body. An interesting fact is that the antibiotics specifically target the bacterial cells and components and do not affect the body of the hosts, in this case, human beings. This development in the field of science, particularly biology, had led to increased advancement in the field of medicine since the fatality rates of many diseases had significantly reduced as compared to the 20th century after the discovery of penicillin in 1928.
I find this part of science to be relevant to my everyday life since it has enabled me to comprehend the work of the antibiotics prescribed to me by a medical practitioner every time that I fall sick. I am now able to appreciate the role played by antibiotics in my treatment as a result of the knowledge that I have gained in this lesson. Therefore, it is valid to say that chapter 4 of this course material has significantly improved my understanding of the working of antibiotics on bacterial cells.
Besides, I have learned the differences between the prokaryotic and eukaryotic cells together with their composition and their cell membranes. It is important to note that cell walls are both in plants and prokaryotes since it helps them to maintain turgidity, thus preventing bursting. On the other hand, animals do not have cell walls but instead contain extracellular matrix. In a close, the topic of the cell membrane in lesson 1 has equipped me with substantial knowledge vis-à-vis the inner workings of the cell as an essential facet of human life.
