Membranes of mitochondria
WebMitochondria-associated membranes (MAM) represent a region of the endoplasmic reticulum (ER) which is reversibly tethered to mitochondria.These membranes are involved in import of certain lipids from the ER to mitochondria and in regulation of calcium homeostasis, mitochondrial function, autophagy and apoptosis.They also play a role in … The inner mitochondrial membrane contains proteins with three types of functions: Those that perform the electron transport chain redox reactions; ATP synthase, which generates ATP in the matrix; Specific transport proteins that regulate metabolite passage into and out of the mitochondrial matrix Meer weergeven A mitochondrion is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi.
