Lactic Acid System

After 10 seconds, the body’s stores of PC are depleted and ATP must be re-synthesized using a different source: The Lactic Acid System Fuel = Carbohydrates (C 6 H 12 O 2 ) i.e. Carbohydrates, Hydrogen and Oxygen

Lactic Acid System Carbohydrates are stored in the body as This is stored in the body in two places - glycogen muscles and liver

Lactic Acid System GlycogenGlucosePyruvic AcidLactic Acid Energy 2 ATP Glycogen phosphorylase Phosphofructokinase (PFK) No O 2 Lactate dehydrogenase (LDH)

Summary Takes place in the Sarcoplasm Produces 2 ATP Is Anaerobic Enzymes = glycogen phosphorylase phosphofructokinase (PFK) and lactate dehydrogenase (LDH) Lactic Acid System

Advantages -more stores of glycogen than PC so lasts longer -relatively simple process, so quick -no O 2 needed so no delay Disadvantages -lactic acid – reduced pH(increased acidity) = prevents enzymes working = fatigue. Lactic Acid System
