ATP into mechanical. It is a massive macro molecule that is involved with the movement of various organelles within the cell. It is also involved with the movement of a cell in its surrounding‚ example: movement of spermatozoa using flagella and movement of paramecium using cilia. It has also been identified to be responsible for movement of vital organelles in a cell‚ for example: movement of organelles in nerve synapses. Thus‚ any dysfunction of dynein could result in major diseases. Dysfunction of

as the place for processes such as cellular respiration‚ metabolism and energy production in the form of ATP‚ or adenosine triphosphate. Many organelles—small structures that help to carry out the daily operations of the cell‚ inhabit the cell such as the Golgi complex‚ the endoplasmic reticulum‚ the nucleus‚ or brain of the cell‚ and lysosomes. An organelle that is the place where most of the cell’s energy is generated is called the mitochondrion. The mitochondrion‚ commonly named “the powerhouse

of the respiratory system. The respiratory system consists of making your body cells get oxygen and eliminate the carbon dioxide cells. The respiration needs the help of the cells each cell has its own respiration by the mitochondria that is an organelle. The main function of the mitochondria is to convert the potential energy of the food or the oxygen molecules into ATP. According to Kimball’s biology pages the cellular respiration is the process of changing the molecules like C6H12O6 + 6O2 + 6H2O

cell and it’s role in cell theory. Since the invention of the electron microscope in 1928 scientists have been able to study the ultrastructure of cells‚ that is‚ parts smaller than what can be seen with a light microscope‚ otherwise known as organelles and their functions. Light microscopes had been developed to a point where the quality of the lenses was not limiting the detail in the image‚ the main limiting factor was the wavelength of light which limits the resolving power‚ the best light

species is very rare. This is because the cells in the animal have organelles‚ which are important for the production of things such as proteins and lipids. Some cells absorb certain wavelengths of light‚ which gives them color‚ as well as melanins and blood supply in the cell‚ which the lens has none off. This alone is not enough for complete transparency‚ though. When the lens is being formed in a fetus‚ it contains organelles‚ but they are destroyed during early development. Although the lens
