Seeing Life Up Close: How a Lab Experiment Sparked My Path to Medicine by Brandon

Seeing Life Up Close: How a Lab Experiment Sparked My Path to Medicine by Brandon - October 2026 Scholarship Essay

As a biology major at the College of Charleston with plans to attend medical school, I have spent many hours in the lab. But one experiment stands out as the moment my curiosity about the human body turned into a calling.

In my introductory biology course, we conducted an experiment on enzyme activity, observing how catalase broke down hydrogen peroxide. We tested how temperature and pH affected the reaction rate, watching bubbles form at different speeds. It was a simple setup, but as I recorded the data, I started thinking about what this meant on a larger scale. Enzymes drive every process in the human body, from digestion to DNA replication. A small change in conditions could speed up or shut down these reactions entirely.

That realization sparked a research question that has stayed with me: how do the molecular mechanisms I was observing in a test tube translate to the complex systems of a living person? I began reading about metabolic disorders, where a single enzyme deficiency can cause serious illness, and how understanding these pathways leads to treatments.

This experiment deepened my curiosity because it connected abstract chemistry to real human health. It showed me that medicine is, at its core, applied biology. Every diagnosis and treatment traces back to the cellular processes I was watching in that lab.

Since then, I have approached my coursework with a new perspective. I am not just memorizing pathways for an exam; I am building the foundation I will need as a physician. That afternoon watching bubbles rise in a test tube confirmed that I am on the right path.
