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.
Evolved from endosymbiosis, chloroplasts are organelles that enable plants and certain algae to convert solar energy to chemical energy. These are lens-shaped organelles with a diameter of about 5Âµm. The chloroplast comprises an aqueous matrix called stroma bound by two smooth membranes - the outer membrane and the inner membrane.
