Glyoxysomes
Glyoxysomes are membrane-bound organelles that contain enzymes able to convert fatty acids into sugar. They are found in the cells of germinating seeds, where the developing seedling relies on its stored fats as a source of sugar -- through a reverse-glycolysis type pathway -- until it becomes capable of photosynthesising on its own. Glyoxysomes belong to the same broad family of single-membrane microbodies as sphaerosomes, which synthesise and store fats in cells such as the endosperm of oil seeds, and peroxisomes, which detoxify substrates …
What this figure shows. A simple diagram of a glyoxysome shown as a membrane-bound sac with an outer membrane enclosing a matrix and a denser central core region. The three parts are labelled Membrane, Matrix and Core, showing how the fat-to-sugar converting enzymes are compartmentalised inside this single-membrane microbody found in the c …
