Detailed explanation-1: -In eukaryotes, the ATP synthase complex is located in the inner membrane of mitochondria, with ATP synthesis reaction occurring on the membrane side toward matrix compartment. In plants, the enzyme is in addition localized in the thylakoid membrane of chloroplasts, with the ATP-forming-moiety facing the stroma.
Detailed explanation-2: -The ATP synthases comprise a very large group of highly conserved enzymes that are found in the bacterial cytoplasmic membranes, the thylakoid membranes of chloroplasts, and the inner membranes of mitochondria.
Detailed explanation-3: -The inner mitochondrial membrane contains many copies of a protein called the F0F1ATPase. This is also called ATP synthase. It consists of two parts: the F0 component spans the membrane and provides a channel for protons to move into the matrix from the intermembrane space.
Detailed explanation-4: -Human mitochondrial (mt) ATP synthase, or complex V consists of two functional domains: F1, situated in the mitochondrial matrix, and Fo, located in the inner mitochondrial membrane.
Detailed explanation-5: -Chloroplasts and mitochondria are the major ATP producing organelles in plant leaves.
