Indicate whether the following statements describes the phosphagen, anaerobic, or aerobic energy system. Sustains exercise for only a few seconds The energy system of choice when the body is at rest A simple energy system in which phosphate is attached to ADP The only substrate for this pathway is glucose (carbohydrate) Includes beta-oxidation, glycolysis, the TCA cycle, and the ETC Requires sufficient oxygen availability Pyruvate is converted to lactate 1. Phosphagen 2. Anaerobic 3. Aerobic

Put the following sequence in order regarding the available sources of energy in skeletal muscle. Creatine, phosphorylated by ATP to creatine phosphate by creatine kinase, provides a high energy phosphate group to energize myosin during the first 15 seconds of explosive muscle activity. Anaerobic glycolysis uses glucose to generate ATP through a series of 10 enzymatic reactions. The time it takes to get glycolysis up and running and providing ATP, including the provision of glucose through the hydrolysis of glycogen, is covered by creatine phosphate. If the muscle is operating at maximal capacity, anaerobic respiration can supply ATP for 30-40 seconds. If exercise persists for more than 30 seconds, aerobic respiration will be required to supply ATP. The reactions of oxidative phosphorylation occur in the mitochondria, require oxygen and are slower than glycolysis but supply much more ATP.

Drag each label to the appropriate position to indicate which energy system is being addressed by the label. Relies on stored levels of high energy phosphates. Utilizes the slowest reaction rates. Describes the complete catabolism of glucose, fatty acid chains, and non-nitrogen containing residues removed from amino acids. Produces 2 molecules of pyruvic acid per molecule of glucose. Produces 36 ATP per molecule of glucose. Produces free creatine phosphate. Utilizes the fastest reaction rates. Can produce large quantities of lactic acid during times of oxygen deficiency. Utilizes creatine kinase. Describes the partial breakdown of glucose. Requires adequate oxygen supply. Occurs in the mitochondria. Immediate energy system. Glycolysis. Oxidative respiration.
