Living organisms are highly organized and structured How does this statement relate to the macromolecules (Proteins, Nucleic Acids, Carbohydrates, and Lipids)? How does this statement relate to the systems (Digestive, Respiratory, Circulatory, Endocrine, etc.)?

Expert Solution

Living organisms are highly organised and structures. The organised structure are maintained by the macromolecules and their high organised processing systems. Macromolecules like DNA, protein, carbohydrates and lipid are important molecules for structural and functional support. DNA codes for particular protein. Macro molecules surrounding by a membranes are called as organelles. Mitochondria, endoplasmic reticulum and ribosomes are examples of some important organelles. DNA is surrounded by a membrane and forms the nucleus. Nucleus and organelles are supported by liquid cytoplasm and surrounded in biological membrane. This unit is termed as a cell. Different membranes are made up of lipids, carbohydrates and proteins (lipo protein, lipopolysaccahride etc). DNA has all the information for living body. It can codes for different proteins which are hormones, enzymes, receptors and ligands. Some are structural proteins and other are functional proteins. Now as we all know cell is the basic unit of life. Bacteria and other prokaryotic organism has a single cells. Other organisms are multicellular, cells organised in different structure to form functional organs.

Single type of cells combined to form a type of tissue. Tissues are group cells having same function. Tissues collectively makes a specific organ (like stomach, kidney and heart). Organs are involve in specific function which is a close circuit of system called as organ system. Different organ systems have different functional properties. For example, circulatory system transports nutrients, minerals, gases and other essential component to the different part of body, endocrine system secrets hormones and respiratory systems helps in respiration. Finally different organ system makes a living organism.
