Among other functions, water enables cells to transport chemicals, helps their temperature remain more stable and keeps the cells turgid. Every living cell on the planet requires water to survive, which is part of the reason scientists suspect that extraterrestrial life is most likely to occur on planets or moons with liquid water. Because water is used to flush toxins from the cell, it must be replenished frequently.Know More
Because water is a polar molecule, it is an excellent solvent, and it can carry a wide variety of dissolved substances in it. This not only helps cells to transport dissolved substances within the cell, but also it helps them to absorb nutrients and expel wastes as well. When a cell is not properly hydrated, such transport functions slow, causing problems for the cell.
Because water has a relatively high specific heat value, it takes a lot of energy to heat up (and cool off), which means that cells do not experience drastic fluctuations in temperature. Stable temperatures help cells to perform more efficiently, as the functions of the cell often slow when the temperature falls and speed up when the temperature rises. Additionally, the water inside a cell helps the cell to remain somewhat pliable, while still retaining its shape.Learn more about Cells
Cells convert high-calorie molecules such as glucose into energy after the sugar molecules pass through the permeable cell wall. This absorption process occurs as a direct result of insulin being released into the bloodstream by the pancreas. When food is eaten, the pancreas releases insulin, which signals the cells to open up and let the glucose molecules in.Full Answer >
Cyclins are the chemicals that regulate the cell cycle. They are part of the family of proteins. There are various types of cyclins, cyclin A, cyclin D, cylcin T, cyclin E and more.Full Answer >
Animal cells are eukaryotic cells, or cells that contain a membrane-bound nucleus. The nucleus holds the DNA of the cell that provides the cell with instructions for life.Full Answer >
Eukaryotic cells have organelles, membrane-bound structures that perform different functions in the cell, and prokaryotic cells do not. Some typical eukaryotic organelles include the nucleus, mitochondria, ribosomes, Golgi apparati and chloroplasts.Full Answer >
