Document Summary
Metabolism set of processes by which cells and organisms acquire, rearrange, and void commodities in ways that sustain life: myriad chemicals + physical processes. Nitrogen metabolism set process by which nitrogen is acquired, used to create proteins and other function nitrogenous compounds, and transferred to elimination compounds (urea, ammonia) Energy metabolism processes by which energy is acquired, transformed, channeled into useful functions, and dissipated. Metabolism divided into: catabolism: chemical compounds are broken down. Elimination: anabolism: synthesize larger complex chemical compounds from smaller chemical building blocks using energy. Metabolism is directed by gene and mediated by enzymes. Make atp faster than the o2 supply to for instance muscles individual must use anaerobic mechanisms: not require o2 lactate dehydrogenase. At point 1 the substrate available is the limiting factor in determining reaction velocity. where as at point 1 to 2 the amount of substrate is increasing therefore the rate reaction velocity is increasing.
