Question

Describe the processes that occur for the immediate energy system

Answer 1

The body utilizes various energy shstems to produce energy required for muscle contraction.
ATP-PC pathway is thd immediate energy system.
ATP PC causes breakdown of creatinine phosphate stored in muscles to generate ATP.
When the carbohydrate reserve in the body depletes the body switches to ATP PC for immediate energy.
Steps for immediate energy system:

1. The ATP stored in myosin cross bridge is broken down to adenosine diphosphate and phosphate.
2. The creatinine kinase breaks down the phospho creatinine stored in body into creatinine and phosphate (Pi)

3. The energy released during breakdown of phosphocreatinine is used to combine the adenosine diphosphate with Pi resulting in ATP formation.
4. This ATP is utilized by muscle cells to contract.
