Oxidative Phosphorylation - PP

Submitted by mtracy on Sat, 12/01/2018 - 20:07


The electron transport chain is the first stage of oxidation phosphorylation. During this phase, Complex 1 strips the electrons off of NADH and Complex 2 strips the electrons of FADH2. These electrons are then donated to coenzyme Q, which in turn donates the electrons to complex 3. Complex 3 then proceeds to donate its electrons to complex 4 which donates to the final electron receptor, oxygen, producing H2O. During this process, complex 1, 3, and 4 pump protons into the intermembrane space and create a concentration gradient. This concentration gradient is used to power ATP synthase, as the protons will naturally flow to an area of lower concentration on the interior of the mitochondrial matrix. To do this, the protons pass through ATP synthase, which rotates its mechanism and powers the synthesis of ATP. For every 3 protons which passes through ATP synthase 1 ATP is generated.



Nice paragraph! I would just try to add more supporting detail in your sentences so that the paragraph sounds more flowy rather than it sounding like a list of steps. Other than that, very informative and well written. 

You may have done this in other paragraphs within the paper, but if not I would define what the acronyms stand for at least once to avoid confusion.  Nice paragraph overall though!
