Concept introduction:
Fatty acids are aliphatic mono-carboxylic acids that are mostly obtained from the hydrolysis of natural fats and oils. They have a general formula
The process of catabolism of fatty acids includes three major parts and they are,
Activation of fatty acid and its transport into mitochondria
Beta-oxidation
Electron transport chain
Fatty acids in the body are mostly oxidized by
Lipogenesis is the
Lipogenesis requires;
Synthesis of fatty acids and glycerol
Activation of fatty acids by CoA and glycerol by glycerokinase
The combination of activated fatty acids and activated glycerol to produce TAG (triacylglycerol)

- If a fatty acid containing 13 carbons is subjected to Beta oxidation, how many molecules of Acetyl CoA can be produced?arrow_forwardShow the first cycle of beta-oxidation of stearic acid. How many ATPs will be generated from the complete oxidation of this fatty acid?arrow_forwardHow many ATP will be broken down in the complete β-oxidation of this fatty acid?arrow_forward
- Which of the following is the chemical end product of fatty-acids metabolized in the beta-oxidation pathway? Select one: a. Beta-carotine b. Free-radicals c. Lactic acid d. Acetyl-CoA e. Pyruvatearrow_forwardDescribe the activation of fatty acids. What is the energy cost for the process?arrow_forwardExplain the mechanism by which beta-oxidation of fatty acids is controlled.arrow_forward
- How many molecules of acetyl-CoA are produced by catabolism of the following fatty acids, and how many b oxidations are needed?(a) Palmitic acid, CH3(CH2)14COOH(b) Lignoceric acid, CH3(CH2)22COOHarrow_forwardWhich of the following statements is/are TRUE about fatty acid activation before β-oxidation? I. The process consumes energy equivalent to two moles of ATP. II. The fatty acid is activated by ATP to give a fatty acyl-CoA.arrow_forwardBefore a fatty acid can undergo β-oxidation, it must be activated and then shuttled across the inner mitochondrial membrane. The activating agent and shuttle molecule are, respectively: A. CoA and carnitine B. CoA and citrate C. acetyl CoA and carnitine D. acetyl CoA and citratearrow_forward
- What impact would an increase in intramitochondrial oxaloacetate have on fatty acid synthesis? Justify your response succinctly.arrow_forwardList three differences between fatty acid synthesis and β-oxidation.arrow_forwardDiscuss the process of digestion and absorption of lipid. Explain the relationships between lipogenesis and citric acid cycle.arrow_forward
