Which molecule is a key regulator of fatty acid oxidation?

Which molecule is a key regulator of fatty acid oxidation?

Step 1: Understand that fatty acid oxidation is the process where fatty acids are broken down to produce energy.
Step 2: Recognize that glucagon is a hormone produced by the pancreas.
Step 3: Learn that glucagon is released when the body is fasting or low on glucose.
Step 4: Know that glucagon helps to increase the breakdown of stored fats (lipolysis) into fatty acids.
Step 5: Realize that by promoting lipolysis, glucagon increases the availability of fatty acids for oxidation, thus regulating the process.
