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 ORIGIN OF MITOCHONDRIA AND CHLOROPLASTS. 1  Eukaryotes possess complex intracellular organelles, such as mitochondria and chloroplasts (such as the spiral chloroplast in the alga Spirogyra). 2  Endosymbiosis refers to a condition in which one cell lives inside another cell for the benefit of both.
