What is the relationship between glucose and triglycerides as skeletal muscle energy substrates as a function of activity level?
What will be an ideal response?
Answer: During low to moderate activity, glucose remains the more important metabolic fuel, with glycogen breakdown being stimulated in both the liver and muscle. With sustained activity, glycogen stores become depleted and triglycerides from skeletal muscle and adipose tissue are mobilized to an increasing extent.
