• High-protein diet
• Low-fat diet
• High-carbohydrate diet
• Prolonged fasting or starvation

refers to a semi-liquid material made up of partially digested food and gastric secretions- a thick semi-liquid material made up of partially digested food and gastric secretion.

• chyme

• saliva

• enzyme

• villi

Which enzyme is responsible for the first step in glycerol metabolism, converting glycerol to glycerol-3-phosphate

• Glycerol dehydrogenase
• Glycerol kinase
• Lipase
• Acetyl-CoA synthetase

Which molecule is an end product of β-oxidation that enters the citric acid cycle for further energy production?

• Glycerol
• Acetyl-CoA
• NADH
• FADH2

What would likely occur if oxaloacetate is depleted during metabolism?

• Fatty acid synthesis would increase
• β-oxidation would cease
• Acetyl-CoA would accumulate, leading to ketogenesis
• Glycogen storage would increase

Triacylglycerols are stored in adipose tissue and are a significant energy reserve in the human body.

• TRUE
• FALSE

Carnitine is essential for the transport of fatty acids into the cytosol for β-oxidation.

• TRUE
• FALSE

Lipogenesis occurs in the mitochondria, where acetyl-CoA is converted into fatty acids through a series of anabolic reactions​.

• TRUE
• FALSE

Beta-oxidation produces acetyl-CoA, FADH₂, and NADH, which are used in the citric acid cycle and electron transport chain for ATP production.

• TRUE
• FALSE

Unsaturated fatty acids does not require additional enzymes like isomerase and reductase to handle double bonds in cis configurations during beta-oxidation.

• TRUE
• FALSE
