The cells build the various systems of the body

Part One 

Molecules of life are metabolized in cell and generate tissues within the body. The cells build the various systems of the body and are studies about disease and health. They indicate the relations between man and their environment ranging from food technology to microorganisms as well as food system sustainability. 

Part Two 

Nutrient metabolism and energy which are essential for sustaining function and life are fundamental principles in the research about metabolism and homeostasis. Minerals and vitamins are molecules of life that control metabolism; they impact genetic expression in addition to supporting living organisms. The responsibility of enzymes in metabolism is crucial in explaining the manner in which nutrients perform their functions in biochemical processes and henceforth psychology. Likewise, the role of phytochemicals and hormones in cellular metabolism offers an essential basis for the comprehension of disease and health. The understanding of the responsibility that catabolism and metabolism play in accomplishing homeostasis puts forward the foundation to address the stress-linked illness that is used to exemplify the biological harm which occurs if homeostasis is not maintained. 

Part Three 

A change in inherited genetic configuration scientifically practical in a population by gene alteration, and as an outcome of natural selection develops into an adaption over subsequent generations. Illustrations specifically knotted to nutrition science comprise lactose intolerance of non-pastoral peoples and lactase tenacity of pastoral residents, vitamin D synthesis as well as the evolution of skin tenor, folic acid eminence and the peril of neural tube birth defects in the likes of spina bifida relative to evolution and genetics, iron absorption and the evolution of hemochromatosis, and the evolution of microbes implicated in foodborne illness. Numerous other inheritable genetic status that may be passed on generationally relating to nutrition science are covered involving diabetes, metabolic disorder, abnormally high blood pressure, celiac disease, allergies, and osteoporosis in addition to Wilson’s disease.   Moreover, nutrients in food regulate gene expression leading to the transcription of DNA, conversion to RNA and henceforth synthesis of proteins. It is fundamental to note that lifestyle, environmental constructs, and lifestyle can promote and initiate DNA damage resulting from the free cell propagation of cancer cells. There are technological advancements linked to evolution and genetics and evolution have altered food supply and led to the increase of antibiotic resistance. An appropriate example is the genetic transformation of many plant food organisms by transgenic and antisense technologies as well as the sub-therapeutic use of antibiotics in traditional animal husbandry both permeates the United States food supply. This form of food system and supply is vastly distinct and contrasted to the evolution of Paleolithic diets as well as dietary recommendations for American citizens. 

Part Four 

The comparisons and interactions between animal and plant kingdoms more so pertaining to nutrient cycling, energy transfer, food chains, food webs in addition to the food system provide many instances for addressing ecological issues. The fusion of vitamin D in people as a result of ultraviolet B exposure from sunlight is an apt illustration of a metabolic and ecologic conception that is linked to evolution, society, and genetics. It is worth noting that vitamin D synthesis is impacted by skin tone, cloud cover, geographical location, clothing among other things. All these constructs combined have contributed to an epidemic of vitamin D deficit as well as various adverse health outcomes involving bone loss, heart disease, multiple sclerosis, inflammation, depression, and allergies. Carcinogenesis is studied alongside latent environmental aspects influencing factors in cancer. Various examples of both adverse and positive interactions of humankind with microorganisms about food production and health indicate the associations among the species of living creatures.
