Verified
The most immediate, but necessarily limited, source of energy for reformation of ATP in muscle cells is ____.
A) aerobic respiration
B) mitochondrial pathways
C) electron transport phosphorylation
D) creatine phosphate
E) anaerobic fermentation
Creatine Phosphate
A high-energy reserve molecule in muscles and the brain that donates phosphate to ADP to regenerate ATP during the first seconds of intense work.
ATP
Adenosine triphosphate (ATP) is a complex organic chemical that provides energy to drive many processes in living cells.

Final Answer :
D
Explanation :
Creatine phosphate is the most immediate source of energy for reformation of ATP in muscle cells because it can donate a phosphate group to ADP, forming ATP, without the need for oxygen or the involvement of mitochondria. However, this process can only sustain energy production for a short period of time before other energy pathways, such as anaerobic fermentation or aerobic respiration, need to be utilized.
