How is metabolism controlled?
Two ways of controlling metabolism – * Coarse control - this controls the amount of enzymes. It is a slow process that includes protein synthesis. * Fine control - this controls the activity of the enzymes. This is a faster process unlike the coarse control, this process changes the activity of the enzymes that are already available in the cells.
Why does reduced metabolism happen? * Our diet – sugary foods can have an impact on our metabolism because of the fluctuation of blood sugar. However there are foods that should be consumed more often to increase our metabolism. If we don’t have the right diet it can cause a few health conditions, for example; if not enough food is not being consumed it can cause a few health problems - in women they might notice their periods are more irregular. More prone to infections and deficiency disease’s like rickets. However if it’s the opposite and has too much food in their diet there is a risk of diabetes, arthritis, heart disease or high blood pressure. * Water - not drinking enough fluids cannot only cause other health problems but it can also slow your metabolism down. * Exercise - more muscle increases your resting metabolic rate. * Stress - this can decrease the body’ metabolic rate because the body is stressed, this can cause less body systems to work efficiently.
