Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many ATP molecules can be replenished from a single creatine phosphate molecule?
A
1
B
3
C
10
D
1000
Explanation: 

Detailed explanation-1: -This process is an important component of all vertebrates’ bioenergetic systems. For instance, while the human body only produces 250 g of ATP daily, it recycles its entire body weight in ATP each day through creatine phosphate. Phosphocreatine can be broken down into creatinine, which is then excreted in the urine.

Detailed explanation-2: -The ATP–creatine phosphate system transfers a high-energy phosphate from creatine phosphate to adenosine diphosphate (ADP) to regenerate ATP. This anaerobic system can provide ATP for approximately 30 seconds for activities such as sprinting and weightlifting.

Detailed explanation-3: -More specifically, Creatine Phosphate can be used to replenish the phosphate group on ATP (the energy coin of the cell) after stores have been depleted through physical activity.
