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 chloroplast is the organelle where photosynthesis occurs, though it is not found in all plant cells (only those on the surface). For example, tubas (e.g. potatoes) and roo â¦ ts do not contain chloroplasts as they have no exposure to sunlight. Bruce Pedersen.
