From the first video, I learned that XY graphs (scatter plots) display relationships between two variables: the independent variable on the X-axis and the dependent variable on the Y-axis. This structure helps identify trends or correlations. I also learned that positive correlation means both variables increase or decrease together, while negative correlation means one increases as the other decreases. Regarding bar graphs, I found it important that they're ideal for comparing distinct groups or categories, such as enzyme activity under different pH levels. These insights helped me select XY graphs to display how temperature, pH, and enzyme concentration affected the reaction rate, and a bar graph to visually compare the average oxygen production in each condition. 2. A fascinating fact from the second video is that catalase can break down up to 40 million hydrogen peroxide molecules per second. This caught my attention because it shows how incredibly efficient enzymes are. Learning about competitive and allosteric inhibition also deepened my understanding of how enzyme activity can be tightly regulated in cells, which is crucial in maintaining balance and preventing damage from reactive molecules like hydrogen peroxide.
