BIOL 100 Lecture Notes - Lecture 1: Disaccharide, Gluconeogenesis, Ribose
Document Summary
Properties of life: energy capture involves redox reactions, all living systems take electrons from food to use as energy. Lysosomes breakdown and digest materials taken in by cells: mitochandria produces atp, supports the critical number of cells, cells sit in intracellular fluid, cell death is apoptosis. Water: approx 60-70% of the human body is water. Of the 60%, 35% is found in cells, If it does not advance, it produces chemical products as a result of fermentation. In aerobic respiration, glycolysis and oxidative phosphorylation are linked, in anaerobic respiration they become unlinked. Two example are lactic acid fermentation in animals, and alcoholic fermentation. Lactic acid, formed during glycolysis when oxygen is not available so pyruvate accept the hydrogen ion from nadh and forms lactic acid: alcoholic fermentation refers to the glycolytic metabolism of yeast cells in an anaerobic environment. Lactic acid minimizes the growth of harmful bacteria: cheese, yogurt, sauerkraut, pickles. Oxidative phosphorylation: mitochondrion is the organelle that produces atp.
