occur. 3. Describe in detail electron transport and oxidative phosphorylation Be sure to include where it occurs in the cell, how the electron transport process operates, describe how ATP is actually generated, all the substrates, products, and other materials necessary for the processes to occur. Lastly, what about these pathways can be considered an advantage and what can be considered a disadvantage? (hint: think about: amount of ATP produced, is oxygen required?, how "fast" are they compared to other means of generating ATP, are the substrates limited?)Explanation / Answer
OXIDATIVE PHOSPHORYLATION is a metabolic pathway in which cells use enzymes to oxidize nutrients thereby releasing energy which is used to produce ATP.
in most eukaryotes ,this takes place inside the mitochondria.
although oxidative phosphorylation is a vital part of mtabolism as it gives energy due to high ATP yield(advantage),it produces reactive oxygen species such as superoxide and hydrogen peroxide, which leads to propogation of free radicals,damaging cells and contributing to disease and possibly aging. the enzymes carrying out this metabolic pathway are also the target of many drugs and poisons that inhibit their activities.(disadvantage)
