Explanation / Answer

5. Foodborne illnesses are infections or irritations of the gastrointestinal tract caused by intake of food or beverages containing harmful bacteria, parasites, viruses or chemicals. The infectious food borne illness is caused by bacteria, virus and parasites. The food borne illness caused by chemicals, pesticide, heavy metals and additives, is noninfectious food borne illness.

14. Anabolic pathway synthesizes molecules and needs energy, whereas the catabolic pathway breaks down

molecules and produces energy. Digestion is essentially a catabolic process, where nutrient substances are ingested and broken down into simpler components for the body to use. In cells, catabolic processes break down polysaccharides ( starch, glycogen, and cellulose) into monosaccharides (glucose, ribose and fructose) for energy. Proteins are broken down into amino acids, for use in anabolic synthesis of new compounds or for recycling. And nucleic acids, found in RNA and DNA, are catabolized into nucleotides as part of the body's energy needs or for the purpose of healing.

18.The thermic effect of food / diet-induced thermogenesis / postprandial thermogenesis, refers to the increase in metabolic rate (the rate at which the body burns calories) after ingestion of food. so it is the energy needed to digest ,absorb and use the nutrients.

6. Pathogens can cause different types of foodborne illness. When a contaminated food is eaten, the pathogens themselves can cause foodborne infection. The toxins produced in the food by pathogens can cause foodborne intoxication. The toxins produced in the body by the ingested pathogens can cause foodborne toxin-mediated infection. Bacteria produces toxin that causes illness characterized by nausea and vomiting 0.5 to 6 hours after the ingestion of the contaminated food product. In Sally's case the illness can be due to enteric toxin/ intestinal toxin which are formed by the microbes when they enter the intestinal tract. Common symptoms of foodborne illnesses caused by preformed or enteric toxins include nausea and diarrhea.

20.The post-absorptive state occurs around three to five hours after food has been completely digested and absorbed. at this state glucose level drops and restored from stored glycogen. So glucagon is the predominant hormone which converts the glycogen into glucose.

21. Glucose is the major source of energy in the absorptive state.
