Document Summary
Metabolism is all the chemical reactions occuring in the body. Enzymes are proteins that catalyze (speed up) chemical reactions. Salivary amylase breaks down the starch amylose into sugars. The energy required to start a metabolic reaction. The amount required is decreased by enzymes. Enzymes are a specialized type of protein that increase the speed of chemical reactions, they can be recycled because they are never modified. Metabolic rates are the measure of a person"s energy use. Depends on speed and efficiency of enzymes. Basal metabolic rate - the energy use of a restful wakeful,person. Cellular respiration: a series of metabolic reactions converting energy from nutrients into atp energy. Atp contains, adenine, a sugar (ribose), 3 phosphate groups. Provides the the energy used by the cell. Phosphorylation - phosphate groups are transferred from atp to another molecule. A living cell constantly performs 3 kinds of work that require energy. 3 types of work provided by atp.
