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.
Okay, great. So how do cells (remember, both plant and animal cells need energy, and neither can directly use the energy provided by the sun) get the energy out of the sugar molecule? They do it with a process called cellular respiration. In cellular respiration, cells use oxygen to break the sugar molecule. That releases the energy which is then transferred to an ATP (adenosine triphosphate) molecule. ATP is the fuel that cells need for energy.
