Does the formamide in EVA foam mats pose a health risk? The French researchers tested three different brands of foam puzzle mats. The study found that any exposure to formamide came almost exclusively through inhalation. Exposure through ingestion (whether through suction, chewing, or swalling a piece) was negligible.
Chemiosmosis is one of the processes by which ATP is synthesized. In eukaryotes, it takes place in the mitochondria during cellular respiration and in the chloroplasts during photosynthesis. In prokaryotes, it occurs in the cell membrane.
DCPIP, the reagent we use to measure rates of electron transport in the thylakoid membrane of isolated chloroplasts, is also an uncoupler. It causes very rapid electron transport in the membrane that is uncoupled from photophosphorylation (ATP synthesis) at concentrations of 50â100 Î¼ M [ , ].
