      Mitochondria Structure and Roles The number of mitochondria per cell is energy/function dependent; i.e., those cells that require and expend the most energy contain the highest number of mitochondria. Most cells have between a few hundred to over 20,000 mitochondria; they are concen-trated most heavily in cells of the heart, brain,

      hot ones to have inherited mitochondria that produce relatively much heat (Ruiz-Pesini et al., 2000). For men, however, there is a catch, because they host one cell type that happens to be particularly sensitive to a loss in ATP: sperm. To be fast, sperm cells need to be small. Typically they accommodate only up to a few dozen

      Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system that takes in nutrients, breaks them down, and creates energy for the cell. The process of creating cell energy is known as cellular respiration. Most of the chemical reactions involved in cellular respiration happen in the mitochondria.

      mitochondria, where they are converted to acetyl CoA. ª Once pyruvate is converted to acetyl CoA, it enters the Krebs cycle (also known as the citric acid cycle). ª The Krebs cycle is an eight–step cycle in which acetyl CoA is added to oxaloacetate, which is further broken down producing CO 2, reduced coenzymes (NADH + H + and FADH 2), and ATP.

      mitochondria fails to produce energy that is needed for the sustainment of life and growth of an organism. Injury in the cell or even cell death results in the production of less energy. If the process happens throughout the body, the whole system begins to fail. The disease primarily affects young.

      This process is called photosynthesis and occurs in the chloroplast of the plant cell. Plants take in carbon dioxide through tiny openings or pores in their leaves called stomata. Special cells in the leaves of plants called guard cells open and close the stomata. Cellular respiration is a process that occurs in the mitochondria of all organisms.
