Approximately 90 hours of flight training instruction, 22 weeks of training. Purpose: teach students basic flying skills. Focus: Contact, Instruments, Formation (2-ship), Navigation. At the end of this 6-month phase, students pick which Advanced Track they wish to fly.
Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components.
Figure Detail. Logically, mitochondria multiply when a the energy needs of a cell increase. Therefore, power-hungry cells have more mitochondria than cells with lower energy needs. For example, repeatedly stimulating a muscle cell will spur the production of more mitochondria in that cell, to keep up with energy demand.
