1.) Explain why chemiosmosis is able to produce more ATP than substrate-level phosphorylation. 2.) Explain the importance of mitochondria and aerobic respiration to multicellular life. 1.) Explain why chemiosmosis is able to produce more ATP than substrate-level phosphorylation. 2.) Explain the importance of mitochondria and aerobic respiration to multicellular life. 1.) Explain why chemiosmosis is able to produce more ATP than substrate-level phosphorylation. 2.) Explain the importance of mitochondria and aerobic respiration to multicellular life.Explanation / Answer
Substrate-level phosphorylation means that a phosphate is transferred to ADP from a high-energy phosphorylated organic compound. The process of pumping protons across the membrane to generate the proton gradient is called chemiosmosis.So, in case of chemiosmosis the Flow of hydrogen ions causing proton gradient release energy. So NADH, FADH will produce 3 and 2 ATP respectively in chemiosmosis. while in substrate level phosphorylation there will be production of only one ATP per substrate or molecule in which phosphate transfer take place.
This is why there is production of energy is higher in chemiosmosis than substrate level phosphorylation.
2. Mitochondria is also known as power house of the cell. As There is production of ATP by cellular respiration inside mitochondria by conversion of fuel (like sugars, fats and amino acids). Adenosine trisphosphate (ATP) is the universal energy currency of the cell.
Cellular respiration involves the utilisation of oxygen for the combustion of fuels which led to the release of energy and hence it is vital for life.In other words cellular respiration takes place inside the cells and consequently the mitochondria involves in production of ATP by aerobic respiration.
