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.
The flow of protons which creates the ATP is chemiosmosis. The ATP can then be used in the light independent stage of photosynthesis or to actively transport potassium ions into the guard cells, so they become turgid as a result of water entering by osmosis.
