Proteins are macromolecules that are passed from the chloroplast to the mitochondria.
The chloroplast is an organelle present inside plant cells immersed in a liquid medium known as cytosol.
Throughout the development of the metabolic processes of a plant, it is the chloroplast that determines which proteins are those that enter and leave through its double lipid membrane from the cell cytosol according to metabolic needs.
- Mitochondrial proteins are first fully synthesized in the cytosol then they are sent to the mitochondria, where there are specific receptors to which they bind to join the organelle, through the translocation process.
- Protein complexes that function as protein translocators participate in the translocation of proteins through mitochondrial membranes.
Therefore, we can conclude that proteins are passed from the chloroplast to the mitochondria.
