Energy systems (BTEC Sport)
What type of reaction is the ATP/PC? - Anaerobic. What chemical is involved in the ATP/PC system? - Phosphocreatine. Where is the site of reaction for the ATP/PC system? - In muscle cells (sarcoplasm). What are the controlling enzymes of the ATP/PC system? - Creatine Kinase. What is the activity of Creatine Kinase effected by? - 1.) Activated by an increase in ADP. 2.) Inhibited by an increase in ATP. What is the Net total of ATP produced by the ATP/PC system? - 1 ATP molecule. What are the by products of the ATP/PC reaction? - 1.) Phosphate group. 2.) Creatine molecule. What is the duration of energy produced by the ATP/PC system? - 2- 10 seconds. What is the intensity of exercise required for the use of the ATP/PC system? - Very high intensity. What are sporting examples of the use of the ATP/PC system? - 1.) Throwing events (shot put). 2.) Sprinting. What is the recovery process of the ATP/PC system? - 1.) Reaction can be reversed. 2.) Requires 180 seconds and 4 litres of oxygen. What type of reaction is the Lactic acid system? - Anaerobic. What is the food/chemical fuel required for the Lactic acid system? - Glycogen. Where is the site of reaction for the Lactic acid system? - In muscle cells (sarcoplasm). What are the controlling enzymes for the Lactic acid system? - 1.) Glycogen Phosphorylase (GP). 2.) Phosphofructokinase (PFK). 3.) Lactate dehydrogenase (LDH). What is the Net total of ATP produced in the Lactic acid system? - 2 ATP molecules. What are the stages of ATP production in the Lactic Acid system? - 1.) Glycogen is broken down by GP into glucose. 2.) Glucose is broken down by PFK into Pyruvic Acid. 3.) Pyruvic acid is broken down by LDH into Lactic acid. What are the By products of the Lactic acid system? - Lactic Acid. What are the effects of the production of Lactic Acid? - 1.) Lowers pH of blood. 2.) Inhibits enzymes. 3.) Causes muscle fatigue and pain. 4.) Inhibits reactions. What is the duration of the energy produced by the Lactic Acid system? - 10 seconds to 2/3 minutes. What intensity of activity is required for the Lactic Acid system to come to use? - High Intensity.
