HSC 332 Lecture Notes - Lecture 2: Glycogen, Phosphocreatine, Activation Energy
Document Summary
* fuel sources from which we make energy (adenosine triphosphate atp) * 1 calorie (cal)=heat energy required to raise 1 g of water from 14. 5 degrees c to. * energy from chemical bonds in food stored in high-energy compound atp. * extra glucose stored as glycogen in liver, muscles. * glycogen converted back to glucose when needed to make more atp. * glycogen stores limited dietary carbohydrate needed in order to replenish. * energy substrate for prolonged, less intense exercise. * yields high net atp but slow atp production. * must be broken down into free fatty acids (ffas) and glycerol. * only ffas are used to make atp. Controlling rate of energy production by substrate availability. * energy released at controlled rate based on availability of primary substrate. * excess of given substrate=cells relying on that substrate more than on others. Controlling rate of energy production by enzyme activity.
