Cancer Epidemiology — Pathophysiology: The Biologic Basis for Disease in Adults and Children▶ 18:40A prime clinical example is inflammation -induced colon cancer, commonly seen in patients with long -standing inflammatory bowel disease, like ulcerative colitisSo if I'm tracking this right, the tissue is so heavily bathed in inflammatory mediators like reactive oxygen species released by macrophages…You've hit the nail on the headLight Reactions of Photosynthesis — Biochemistry▶ 29:27Under bright sunlight, excess energy can induce highly damaging photochemical reactions involving oxygenLeading to the formation of lethal reactive oxygen speciesLike superoxide or hydroxyl radicals, carotenoids quickly quench these dangerous intermediates, preventing massive cellular damageOxidative Phosphorylation and Mitochondrial Function — Marks' Basic Medical Biochemistry: A Clinical Approach▶ 7:27Yes, because it can exist in a half -reduced state, a semiquinoneIt's prone to accidentally passing an electron directly to oxygen, creating superoxide, a damaging reactive oxygen species, or free radicalThe cell has defenses, but it's a known hotspot for generating these
