sejtfunkciói
Sejtfunkciói refers to the various roles and activities that a cell performs to maintain life and carry out its specific purpose within a multicellular organism or as a single-celled entity. These functions are essential for survival, growth, reproduction, and interaction with the environment. Key cellular functions include metabolism, which encompasses all the chemical processes that occur within a cell to sustain life. This involves the breakdown of nutrients to release energy (catabolism) and the synthesis of complex molecules necessary for cellular structure and function (anabolism). Another crucial function is transport, where cells regulate the movement of substances across their plasma membrane. This includes taking in essential nutrients and expelling waste products, as well as maintaining specific internal ion concentrations.
Cells also perform a variety of specialized functions depending on their type. For example, muscle cells contract
