Question

which of the following acts as an energy reserve in muscle to quickly create more atp?

a.) creatine phosphate
b.) lactic acid
c.) pyruvic acid
d.) glycolysis

Explanation:

Identify the function of creatine phosphate

Creatine phosphate (or phosphocreatine) stores high-energy phosphate bonds in muscle cells, allowing for the rapid transfer of a phosphate group to ADP to regenerate ATP during the first few seconds of intense muscle contraction.

Evaluate the other options

• Lactic acid is a byproduct of anaerobic glycolysis, not an energy storage molecule.
• Pyruvic acid is an intermediate product of glycolysis.
• Glycolysis is a metabolic pathway that breaks down glucose, not a storage molecule.

Answer:

• a.) Creatine Phosphate (Correct answer)
• b.) Lactic Acid
• c.) Pyruvic Acid
• d.) Glycolysis
