The organelles that are both surrounded by a double membrane, have their own DNA, are involved in energy metabolism, and have their own protein synthesis machinery are Mitochondria, and Chloroplast.
Mitochondria- The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular). Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP).
Chloroplast- Organelles found in plant cells called chloroplasts use the photosynthetic process to change energy from the sun into reasonably stable chemical energy. They maintain life on Earth in this way.
