Fatty Acid Beta Oxidation Quiz

What is the basic structure of a fatty acid?

• A fatty acid consists of a methyl group (CH3) at one end and a hydroxyl group (OH) at the other end.

• A fatty acid consists of a methyl group (CH3) at one end and a carboxyl group (COOH) at the other end.

• A fatty acid consists of a methyl group (CH3) at one end and an amino group (NH2) at the other end.

• A fatty acid consists of a methyl group (CH3) at one end and a phosphate group (PO4) at the other end.

What is the first step in fatty acid activation?

• Conversion of fatty acids to fatty acyl-AMP

• Conversion of fatty acids to fatty alcohols

• Conversion of fatty acids to fatty acyl-CoA

• Conversion of fatty acids to fatty acyl-carnitine

What is the role of the carnitine shuttle in fatty acid beta oxidation?

• Transporting short-chain fatty acids into the mitochondria for beta oxidation.

• Promoting the synthesis of fatty acids in the cytoplasm.

• Transporting long-chain fatty acids into the mitochondria for beta oxidation.

• Inhibiting the beta oxidation of fatty acids.

How many steps are involved in beta oxidation of fatty acids?

• 6

• 4

• 2

• 8

What is the final product of beta oxidation of fatty acids?

• Pyruvate

• Glycerol

• Oxaloacetate

• Acetyl-CoA

What is the rate-limiting enzyme in beta oxidation?

• CPT-II

• CPT-III

• CPT-IV

• CPT-I

What is the main regulatory mechanism of beta oxidation?

• activity of glycolysis pathway

• availability of amino acids in the cell

• presence of glucose in the cell

• availability of fatty acids and energy needs of the cell

What is the purpose of beta oxidation in the body?

• To break down carbohydrates into glucose for energy production.

• To convert amino acids into glucose for energy production.

• To break down fatty acids into acetyl-CoA for energy production.

• To convert glucose into fatty acids for storage.

What happens to the acetyl-CoA produced during beta oxidation?

• Converted into glucose

• Enters the citric acid cycle

• Used for fatty acid synthesis

• Excreted as waste

How is beta oxidation different from alpha oxidation?

• Beta oxidation breaks down fatty acids into acetyl-CoA, while alpha oxidation breaks down branched-chain fatty acids.

• Beta oxidation breaks down fatty acids into glucose, while alpha oxidation breaks down branched-chain fatty acids.

• Beta oxidation breaks down branched-chain fatty acids, while alpha oxidation breaks down fatty acids into acetyl-CoA.

• Beta oxidation breaks down fatty acids into glycerol, while alpha oxidation breaks down branched-chain fatty acids.
