Document Summary

Catabolic processes to generate high energy compounds that drive biosynthetic pathways. Stage 1 building blocks: breaking things down into individual building blocks. Each are broken down into acetyl co-a or pyruvate intermediates as these are precursors for molecules that can produce energy. Release of products generally when maximal energy has been produced. Oxidative degradation of complex nutrient molecules from the environment or cellular reserves leading to the formation of simpler molecules. Nad+ plays a big role in catabolism since catabolism is mostly oxidative. Nadh oxidation which leads back to nad+ serves to generate more atp. Varied and complex biomolecules are assembled from simpler precursors. Input of chemical energy is necessary to drive these endergonic processes. Mostly reductive reactions performed by nadph (known as the carrier of electrons from catabolic reactions to anabolic reactions) Limited collection of precursors are sufficient to provide for the synthesis of almost any cellular constituent.
