Study Notes
Energy Substrate for Muscle During Prolonged Exercise
- During prolonged low-intensity exercise lasting for more than 40-50 minutes, the major energy substrate for muscle is fatty acids.
Fatty Acid Uptake by Muscle Cells
- Muscle cells can obtain fatty acids from the bloodstream, where they are bound to albumin.
- Fatty acids can also be released from stored triglycerides in adipose tissue.
Fatty Acid Entry into Mitochondria for β Oxidation
- The first step in the process of fatty acids entering the mitochondria for β oxidation is the activation of fatty acids to form acyl-CoA by the enzyme acyl-CoA synthase.
