Document Summary
Add (and chloroplast) at the end of the 3rd point of learning objective) Mitochondria are essential for many physiological functions: metabolism, response to stress. Involved in making sure that the cell is able to deal with stress on cellular structures; increase temp, ph, acids, reactive compounds etc, so that cell can survive: cell death. Making sure cells die when they have to, important for growth, embryo development, must be done in a structured way: calcium storage. One of the area inside cell where a lot of calcium is stored. All different areas of mitochondria have different functions; different proteins, different compositions: centrifugation, subcellular fractionation, differential centrifugation, density gradient centrifugation. Most of the potential energy stored in atp that is available to drive cellular reactions is found in the bonds between the phosphate groups. Cells may have up to 3000 different enzymes. All have different functions, different locations, all enzymes are proteins, not all proteins are enzymes.
