BIO 4307 Lecture 17: Energy Utilization and Glycolysis
Document Summary
Heterotrophs vs autotrophs: heterotrophs use the energy and building materials made by autotrophs, energy is utilized to power various forms of cellular work be aware of examples of each, mechanical work, muscle contraction, cellular movement. Synthetic work: making stuff: fatty acids, amino acids and sugars, specific principles guide our understanding of energy flow in living systems. Fuels are degraded and macromolecules are synthesized in step-wise reactions: metabolism is the conversion of one biochemical to another in a defined and regulated manner. It is a series of related reactions from metabolic pathways. It usually involves energy transduction: catabolic pathways are energy producing. This electron exchange is balanced with a proton transfer as well. Involves electron transfer during oxidation of carbon-based molecules-in the form of hydride ion: fats are a better energy source that carbohydrates- review lipids lecture, be familiar with common activated carriers (electron carriers) and the ultimate electron acceptor (o2) Be familiar with the roles and structural characteristics of nadh,
