Sperms And Creatine Kinase

 

Creatine Kinase aka Creatine Phosphokinase 

CPK Isoenzymes 

Creatine Kinase

Provides Rapid Regeneration Of ATP When ATP Is Low 

Male Sperm 

Components Of Sperm 

Sperm Contains Creatine Kinase 

Energy Supply:

• Sperm require a large amount of ATP (adenosine triphosphate) for flagellar movement (swimming).

• Creatine phosphokinase facilitates the reversible conversion of:

  $$\text{<span style="font-size: large;"><span style="color: red;"><b>Creatine + ATP</b></span></span>}<span\; style="font-size:\; large;"><span\; style="color:\; red;"><b>\rightleftharpoons </b></span></span>\text{<span style="font-size: large;"><span style="color: red;"><b>Phosphocreatine + ADP </b></span></span> }$$

• This reaction acts as an energy shuttle, helping maintain ATP levels in the sperm tail (flagellum).

• CK is highly localized in the midpiece of the sperm, where mitochondria are concentrated.

• This area is the powerhouse for sperm motility.

• Fertility Research: Used as a biomarker in studies on male infertility, particularly in assessing sperm viability and energy dynamic.
