CHM361H5 Lecture Notes - Lecture 1: Mitochondrion, Supramolecular Assembly, Cellular Respiration
Document Summary
Ionic equilibria - acids and bases, ph buffers. Composed of many cells, which possess organelles, composed of macromolecules. Conformation of macromolecules is a consequence of interactions between the monomeric units, according to their individual chemical properties. True for macroscopic structures e. g. organs, leafs, but also for microscopic structures. True for macroscopic structures e. g. organs, leafs, but also for microscopic structures e. g. cells, and chemical compounds. Living systems are actively engaged in energy transformations. Maintenance of highly organized structure and activity of living systems depends on their ability to extract energy from the environment, and maintain their complex structure. The sun is the ultimate source of energy - which flows through food chains. Thus, the biosphere is a system through which energy flows. Atp and nadph are 2 most prominent examples of special energized biomolecules. They represent the chemically useful forms of stored energy. Only upon death does an organism reach equilibrium with its inanimate environment.
