Some errors I've found and fixed myself:
- Glycolysis does not produce FADH2, but the lead of Glycolysis said it did for nearly 5 months, and the error was viewed ~250,000 times.
- Glycerophospholipids are not "almost exclusive to plant and animal cell membranes", but Glycerophospholipid said they were for nearly 2 years, and the error was viewed ~150,000 times.
- T cells cannot also be called "thymocytes", but the lead of T cell said they could be for over 5 months, and the error was viewed ~250,000 times.
- Protein-coding genes comprise ~28% of the human genome, but C-value enigma said ~1.5% for 5.5 years, and the error was viewed ~100,000 times.
- Pyruvate carboxylase is present in muscle, but the lead of Pyruvate carboxylase said it wasn't for over 7 years, and the error was viewed >150,000 times.
- Cyclic photophosphorylation does not involve photosystem II, but Photophosphorylation said it did for over 6 months, and the error was viewed ~50,000 times.
- Water potential is not the opposite of osmotic potential, but the lead of Osmotic pressure said it was for 6.5 years, and the error was viewed ~2,000,000 times.
- Transposons are not "primarily prokaryotic", but we classified them thus for nearly 3 years in a NavBox transcluded in 17 articles.
- This is not a type II survivorship curve, but Survivorship curve said it was for nearly 5 years, and the error was viewed >200,000 times.
- Endothermic process was vandalised to give "cooling ice" as an example, and the error persisted for nearly 4 months and was viewed ~50,000 times.
- Humans do not produce 50% male offspring, but Y chromosome said they did for over 20 months, and the error was viewed >400,000 times.
- These two images incorrectly included CO as one of the gases in the Miller-Urey experiment, and the error stood for nearly 7 years, was viewed >1,000,000 times on the English Wikipedia, and propagated to 25 other language Wikipedias.
- And the winner is...
- The casein:whey ratio in milk varies greatly between species, but Milk just said it was around 80:20 for over 12 years, and the error was viewed over 3.5 million times just in the last four years.

"Cell wall" could be misunderstood to mean "peptidoglycan layer", likely explaining the confusion. The version before the addition of the error was misleading.
