Explain Chemical changes during muscular contractions?
The chemical changes during muscular contractions include conversion of ATP into ADP, break-down of phosphocreatine and muscle glycogen, formation of Fructose diphosphate and lactic acid and resynthesis of creatine phosphate.
What is the function of ATP-PC or CP?
ATP-PC (adenosine triphosphate-phosphocreatine) system provides immediate energy for short bursts of high-intensity activity by regenerating ATP from phosphocreatine. It works as the primary energy source during activities such as sprinting or lifting heavy weights.
What is the backup energy molecule that can be rapidly converted to ATP in active skeletal muscle?
Phosphocreatine
What energy system is used at the beginning of exercise and during high intensity short duration exercise?
The phosphagen system, specifically involving creatine phosphate, is primarily used at the beginning of exercise and during high-intensity short-duration exercise. This system provides quick energy through the breakdown of creatine phosphate to regenerate ATP, which fuels muscle contractions during these intense activities.
What is the chemical equation for the resynthesis of ATP?
The chemical equation for the resynthesis of ATP is ADP (adenosine diphosphate) + Pi (inorganic phosphate) + energy → ATP (adenosine triphosphate). This process primarily occurs during cellular respiration in the mitochondria, where ATP is regenerated using the energy released from the breakdown of glucose or other energy sources.
What is the predominant energy system used in strength activities?
ATP/PC system (Phosphocreatine system) are predominantly used in strength activities such as a weight-lifter or a tennis serve.
What energy system is being used in 100m sprint?
ATP-PC system Adenosine triphosphate.- phosphocreatine phosphocreatine is broken down into phosphate and creatine molecules. as with any bonds that are broken energy is released. The phosphate molecule bonds to ADP (adenosine diphosphate) which produced an ATP molecule. This ATP molecule is used within cells to make energy.
What does ATP PCr stand for?
ATP PCr stands for Adenosine Triphosphate PhosphoCreatine, which is a system in the body that provides rapid energy through the breakdown of phosphocreatine to regenerate ATP during short bursts of intense physical activity.
What does ATP CP stand for?
adenosine triphosphate phosphocreatine system :)

What is phosphogen?
The Phosphogen SystemSkeletal muscle uses large amounts of ATP during active contraction. Skeletal muscle can produce limited amounts of ATP from the breakdown of stored phosphocreatine. As ATP is used and ATP levels decrease, phosphocreatine is used to make ATP from ADP. When the cell is resting and ATP levels increase due to aerobic glucose catabolism, phosphocreatine is produced from ATP and creatine. This mechanism can produce 1 ATP for every molecule of phosphocreatine present. Muscle cells normally have enough phosphocreatine to produce ATP for several minutes at rest but only 10-15 seconds during exercise.
What is the phosphate energy System?
The phosphate energy system, also known as the ATP-PC system, is a short-term energy system used during high-intensity activities lasting up to 10 seconds. It involves the breakdown of stored ATP (adenosine triphosphate) and PCr (phosphocreatine) to provide immediate energy for muscle contractions. This system does not require oxygen and is essential for activities such as sprinting and weightlifting.
Where does the ATP-PCr system take place in the cell?
The ATP-PCr system takes place in the cytoplasm of muscle cells. Phosphocreatine (PCr) stores high-energy phosphate bonds that can be used to quickly regenerate ATP during short bursts of intense energy production. This system helps provide rapid energy for activities like sprinting or weightlifting.
Phosphocreatine Energy System waste products?
The waste products of the Phosphocreatine energy system are inorganic phosphate and adenosine diphosphate (ADP). These byproducts are produced when phosphocreatine donates a phosphate group to replenish ATP levels during high-intensity, short-duration activities such as sprinting or weightlifting.
ATP and phosphocreatine are major energy sources for events lasting how long?
10
What is the backup energy molecule that can be rapidly converted to ATP in active skeletal muscle?
Phosphocreatine
