Document Summary

Energy production in terms of food and digestion is a psns effect. You have money coming in and you are putting it into the bank. The sns and the stress system is taking the money out of the bank and spending it to deal with certain stresses. You should know the key components that are coming in, and knowing that they all eventually feed into the citric acid cycle. If there is a lack of glucose in the diet, then glucose can be made by gluconeogenesis. In most cases, if there is a lack of glucose in the diet, then a number of organisms will utilize fatty acids as an energy source. Gh is produced by the anterior lobe of the pituitary. Somatotrophs have two effective controls that come from the hypothalamus. Somatotrophs are either under positive control or negative control.
