(EN-zimes) working proteins that speed up specific chemical reactions, such as releasing energy from nutrient molecules, without themselves being altered in the process. 3. non-enzyme proteins of cells, such as the proteins of the cell membrane and of its interior structures. 4. structures of mostly coiled DNA and proteins, housed in the nucleus of every cell. The DNA carries the genes for making cellular proteins; the protein and other constituents influence the configuration and functioning of the DNA. 5. cells that specialize in the storage of fat and form the fat tissue. Fat cells also produce fat- metabolizing enzymes; they also produce hormones involved in appetite and energy balance. 6. a genetic variation present from birth that may result in disease. 7. an inborn error of metabolism that interferes with the body’s handling of phenylalanine (from dietary protein) and, left untreated, results in serious harm to the brain and nervous system. 8. groups of cells working together to perform specialized tasks. Examples are muscles, nerves, blood, and bone. 9. discrete structural units made of tissues that perform specific jobs. Examples are the heart, liver, and brain. 10. a group of related organs that work together to perform a function. Examples are the circulatory system, respiratory system, and nervous system.
