BIO 110 Midterm: Test 3 Notes
Document Summary
The entire network of chemical reactions in a living cell, with or without enzymes. Catabolism (breaking down) and anabolism (building up) One regulation in first step is often enough to regulate the whole path, or there is a. Catabolism is oxidative (losing electrons) while anabolism is reductive (adding step with large - g electrons) Catabolism is in the mitochondria or cytoplasm, anabolism is in the cytoplasm. Because when producing atp, there are dangerous products that are hazardous if they"re in the cytoplasm. Damage by reactive o2 is restricted to just the mitochondria. Metabolic pathways aren"t independent and intersect like traffic in a road. Manipulation of one pathway can impact the others. Most ancient pathways are hubs of metabolism. G tells us which direction the pathway is going. They tend to alternate between + and - in metabolic pathway. G is spontaneous and favorable; + g is nonspontaneous and unfavorable.
