Due on Sept. 24 by 8:00 AM Discussion 1 – Some antibiotics act by binding to certain enzymes in the target bacteria. Describe the mechanism of enzyme action. How might these antibiotics influence the chemical reactions controlled by the enzymes? What is the anticipated effect on the bacteria? On the person taking the antibiotic prescription? Dicussion 2- In the last module, we discussed the legal use of DNA analysis in forensic medicine. In this discussion, we will take a look at some of the internal machinery of the cell. Organelles are essential for specific functions associated with a cell. For example, you would expect to find an abundance of mitochondria in a cell involved in energy requiring process, such as active transport of an ion. Select an organelle and discuss what functions might be effected in the body if this organelle was defective. Dicussion 3- Epithelia form continuous sheets of cells that cover surfaces in our body. They are important in the formation of membranes which act as a barrier and interface between compartments of the body. Choose an area of the body covered by epithelia (different from the ones your classmates have chosen) and explain how a break in this epithelial barrier might affect the functioning of a specific body membrane.

Introduction Understanding cellular mechanisms and their impact on human health is essential in biology and medicine. The role of enzymes, organelles, and epithelial tissues is fundamental to maintaining proper physiological functions. This essay will explore how antibiotics interact with bacterial enzymes, the consequences of defective organelles, and the implications of epithelial barrier breaches. Antibiotics and Enzyme Mechanisms Many antibiotics target specific bacterial enzymes to inhibit bacterial growth or kill bacteria directly. These enzymes often catalyze vital reactions essential for bacterial survival, such as cell wall synthesis or DNA replication (Madigan et al., 2018). When antibiotics bind to these enzymes, they typically inhibit their activity by either blocking the active site or altering the enzyme's shape. This disruption prevents the enzymes from catalyzing their normal reactions, leading to a halt in critical bacterial processes. As a result, bacterial proliferation is suppressed or bacteria are killed. On the human host, antibiotics do not usually affect human enzymes due to selectivity, but some side effects can occur if beneficial microbiota are affected. Overall, enzyme inhibition is a strategic approach to combat infections effectively. Impact of Defective Organelles Organelles are specialized structures within cells that perform specific functions necessary for cellular vitality. The mitochondria, for example, generate most of the cell's energy via ATP production through oxidative phosphorylation (Alberts et al., 2014). If mitochondria become defective, energy production declines, impairing tissues with high energy demands such as muscles and the brain. This can lead to symptoms like muscle weakness, neurological deficits, and fatigue. Similarly, defects in lysosomes can impair waste degradation, causing buildup of cellular debris and contributing to lysosomal storage diseases. The disruption of organelle function often results in cellul
