Final answer:
Of the options listed, glycogenesis is the process not involved in fat absorption or metabolism; it pertains to the formation of glycogen from glucose and is associated with carbohydrate metabolism, not fat.
Step-by-step explanation:
The part of fat absorption and metabolism that is NOT involved is e. Glycogenesis.
Glycogenesis is the process of glycogen synthesis, in which glucose molecules are added to chains of glycogen for storage. Whereas, lipogenesis is the synthesis of fatty acids and triglycerides, which occurs in the liver and adipose tissues. Beta oxidation is the catabolic process by which fatty acid molecules are broken down in the mitochondria to generate acetyl-CoA, which enters the citric acid cycle and is used to produce ATP.
Chylomicron formation is the packaging of triglycerides and cholesterol into chylomicrons for transport out of the intestinal cells. Formation of ketones, or ketogenesis, happens when there is an excess of acetyl-CoA in the liver due to the prolonged breakdown of fatty acids, leading to the production of ketone bodies.
