Final answer:
The animal storage form of triglycerides is Fat (A). Triglycerides, which are made up of glycerol and three fatty acids, serve as a key form of long-term energy storage in animals, distinct from starch in plants.
Step-by-step explanation:
The animal storage form of triglycerides is Fat (A). In animals, triglycerides function as a form of long-term energy storage and are composed of glycerol and three fatty acids. Unlike plants, which use starch for energy storage, animals can synthesize most of the fatty acids they require. Triglycerides can be synthesized and degraded via glucose catabolism pathways, glycerol is phosphorylated to glycerol-3-phosphate which enters glycolysis, and fatty acids are broken down in beta-oxidation within the mitochondria, resulting in two-carbon units that enter the citric acid cycle.
