Document Summary
Explain what a metabolic pathway is, what ux is, and the difference between catabolism and anabolism. Based on g, predict whether a reaction in a pathway is likely to be regulated. Compare and contrast regulation of enzymes in metabolic pathways by allostery and by covalent modi cation of proteins. The sum of all the chemical reactions that are occurring in your cell. Some pathways are catabolic, and others are anabolic. Catabolic: breaking larger molecules down into smaller ones, usually extract energy, oxidative, also get reducing power. Anabolic: building larger molecules form smaller ones, ex. building glycogen, etc, usually requires energy input and reducing power input, source of electrons needed. Ux = rate of conversion of a to e. Conversation is ef cient when net g for whole pathway is negative. Pathway is often you have the cell acting on something to make something else, and something else, etc.
