create a road map for all these content to be learned on the central idea of metabolism. The topics are requirements of metabolism, what is energy, forms of energy, chemical bonds are a type of chemical energy, 1st law of thermodynamics (energy conversion), 2nd law of thermodynamics (entropy), chemical reactions release or require energy, oxidation and reduction reactions, redox reaction in the electron transport chain, ATP, ATP hydrolysis, enzymes, enzyme function, enzyme structure, activation energy, enzyme inhibition, factors affecting enzyme activity, transport of substances across membranes, concentration gradient, types of transport mechanisms (passive transport: simple diffusion, osmosis, facilitated diffusion) Active transport (transport using vesicles -endo and exocytosis, and membrane transport using pumps i.e. Na-K pump). The road map should connect from the simplest idea to the highest. See more
