    Cells in eukaryotes (organisms with cells containing nucleus) produce 34 ATP molecules in cellular respiration, and prokaryotic cells (no nucleus) produced 36 ATP molecules. However, two more ATP molecules are produced 'as a net gain' in the process of glycolysis, therefore eukaryotic cells produce a total of 36 ATP molecules and prokaryotic cells produce a total of 38 ATP molecules during cellular respiration (CliffNotes). Eukaryotic cells lose 2 ATPS because the NADH molecules are used for glycolysis to go through the mitochondrial membrane.

    Process of Breathing:Breathing:__
    When there is a movement of breathing, the route that air takes looks like this:
    Air is inhaled through the nose then is taking the nasal route. The nose humidifies and damps the air before reaching the lungs, and also assists with eliminating redunant particles such as dust and soot using the nostrils. At the end of the nasal route, there is a pharynx. Pharynx is 13cm long and is in a funnel tube shape, which is split into 3 sections. This part of the respiration system broadens the reaer of the nasal cavity, sent down to the second carilage of the treachea. The air proceeds ino the larynx, going through the glottis (cavity in the vocal chords). The larynx protects the food from entering the trachea during digestion. After the larynx, there is a trachea. The trachea is backed up with carilage, which then also splits into two sections called a bronchi. Each of the bronchi is connected to each part of the lung, and is again composed with smaller tubes called the bronchioles. These bronchioles then transport air into the alveoli.

    4. Fermentation - This happens in the Cytoplasm, when there is not enough oxygen for the Krebs Cycle, so they use an anaerobic respiration. The purpose of fermentation is to preserve electron carriers for future use, this process produces less ATP due to the lack of the electron transport chain and the Krebs Cycle. In human the waste product is lactic acid, in yeast (fungi) the waste products are ethanol and carbon dioxide.

    A comparison of ATP cell with Battery for extra understanding:
    ...
    As we can see from the two diagrams, ATP is very similar to a camera battery. Both ATP and the battery provide the energy for the object or organelle that is in need of that energy. Both the battery and the ATP molecule has its energy used up during the process of energy reaction between the object and the energy provider (ATP or the battery). The only difference between the ATP molecule and the camera battery is while the reaction between the ATP molecule and the organelle (or process) is while the energy given off the reaction in the camera is gradual, the energy given off the ATP reaction is instant, therefore the need to recharge the ATP molecule with more Phosphate is more instant.

    Respiration is mesured in respiration rate, that is the measurement of numbers of breath taken within a set amount of time, mostly 60 seconds. The average respiration rate of an adult is 12 to 20 beaths per minute.

    3. Electron transport chain - happens in the mitochondria cristae, requires oxygen. The products of the Krebs cycle enters the transport chain then they are oxidase to create a proton gradient. This gradient provides the necessary energy to add a phosphate group to ADP which turns it into ATP with all of them chemical product from the Krebs cycle. This product produces 36 ATP molecules. The waste product is water.
    4. Fermentation - This happens in the Cytoplasm, when there is not enough oxygen for the Krebs Cycle, so they use an anaerobic respiration. The purpose of fermentation is to preserve electron carriers for future use, this process produces less ATP due to the lack of the electron transport chain and the Krebs Cycle. In human the waste product is lactic acid, in yeast (fungi) the waste products are ethanol and carbon dioxide.

    A comparison of ATP cell with Battery for extra understanding:
    ATP in short is an energy carrier in a cell and when a cell needs the energy it gets it from the ATP molecules. This If we compare an ATP to a Rechargeable battery then they are very similar. When a small machine like a remote runs out of energy then we insert the battery and the remote is ready to be used again. An ATP molecule is composed of one adenosine group and 3 phosphate group. When used then the ATP breaks off one phosphate for energy usage and the ATP becomes ADP (with 2 phosphate group left). Then the ADP goes to the Mitochondria where the ADP has another phosphate attaches to become ATP again. If we compare then a full battery is equal to an ATP, a used up battery is like an ADP ( ATP after donating a phosphate group) and when we charge the battery it is the same as when the ADP goes to the Mitochondria to have another phosphate group added to it.

    Diagram Key points:
    Lungs: The lungs are the important, vital, element of the respiratory system. The lungs are located on both sides of the heart, the left and right lung. The lungs function is to transport the oxygen inhaled into blood and to release carbon dioxide from the blood to the atmosphere.
    Nasal cavity: What this part of the respirative system is does is warm, filter and moisten the incoming air from the nose
    Pharynx: Here the throat divides into the trachea (wind pipe) and oesophagus (food pipe). There is also a small flap of cartilage called the epiglottis which prevents food from entering the trachea. Although not display in the diagram the Pharynx is located near the larynx a bit above it.
