Oxidative

... organisms that I know of are either reptiles or other cold-blooded animals, or plants, which all have low metabolic rates and thus probably less oxidative damage and defects resulting from that. Size has similar effect: small animals have fast metabolism and usually also die earlier. Then again, ...

... confused. plants also carry out cellular respiration, which consists of glycolysis (which occurs in the cytosol of cells) and citric acid cycle + oxidative phosphorylation (which occur in the mitochondria of cells). Independently from this, plant cells also carry out photosynthesis, where water ...

... chain --> produces a total of 32 ATP So here is what i am confused about. For plants, they go through photophosphorylation instead of the oxidative phosphorylation (electron transport chain) in which the photophosphorylation produces ATP and NADPH which is used in the Calvin cycle to produce ...

... cycle is the second part of whole process of producing energy for the cell. The cycle produces nadph and fadh which are used in the the 3rd part oxidative phosphorylation in mitochondria where H ions are pumped out to provide enough energy to phosphorylate ADP to ATP. Kreb cycle just takes in ...

Well, I guess there is at least one good example of "anti-aging" mutations: birds seem to have evolved to be more tolerant to oxidative stress from their metabolism, and thus most birds live considerably longer than most mammals of similar size. This is due to mutations in the genes ...
