When young rats are placed on a completely fat-free diet, they grow poorly, develop a scaly dermatitis, lose hair, and soon die.
These symptoms can be prevented if linoleate or plant material is included in the diet.
What makes linoleate an essential fatty acid?
Animals lack the enzymes required to synthesize long-chain fatty acids with 14 or more carbons.
Animals lack the enzymes required to synthesize odd-number fatty acids.
Animals lack the enzymes required to synthesize polyunsaturated fatty acids.
Animals lack the enzymes required to introduce double bonds into fatty acids beyond the A9 position.
One example of a stage 1 reaction in the heterotrophic breakdown of food molecules is:
the intramitochondrial digestion of pyruvate into carbon dioxide and water
the intramitochondrial digestion of fatty acids into carbon dioxide and water
the extracellular digestion of triglycerides into fatty acids and glycerol
the intracellular digestion of some amino acids into NH4+ and pyruvate
the intracellular digestion of glucose monomers into pyruvate
One example of a stage 3 reaction in the heterotrophic breakdown of food molecules is:
the intramitochondrial digestion of fatty acids into carbon dioxide and water
the intracellular digestion of glucose monomers into pyruvate
the intracellular digestion of some amino acids into NH4+ and pyruvate
the extracellular digestion of polypeptides into amino acids
the extracellular digestion of triglycerides into fatty acids and glycerol

However, to make full use of the nutrients released by bacterial action, a rabbit must produce and eat a special type of feces. Why must the rabbit reswallow this material to obtain the nutrients released by bacterial action?Some people who have gallstones experience pain after they eat, with fatty meals causing the greatest discomfort. Why do such meals trigger gallbladder pain? Diabetes insipidus is a medical disorder in which a person produces an unusually large amount of highly dilute urine. Some cases are caused by a gene mutation, but in most people, diabetes insipidus arises after a head injury. Explain how an injury to the head could affect kidney function.Marine mammals and desert rodents both have highly efficient kidneys that produce only a tiny amount of very concentrated urine.
