1. Describe the processes by which fatty acids are transported in the blood, activated and transported into the matrix of the mitochondria for breakdown to obtain energy. (Specifically, determine the role of carnitine palmitoyl transferase in the oxidation of fatty acids.) 2. Explain the processes by which fatty acids are released from triacylglycerol stored in adipose tissue. 3. Outline the β-oxidation pathway by which fatty acids are metabolized to acetyl-CoA and explain how this leads to the production of large...
