Why some of the activities of Mitochondria and Chloroplasts are not regulated by the Nucleus?
Answers
Answer:
Chloroplasts and mitochondria are the self autonomously replicating organelles and they have specific roles such as photosynthesis occurs in chloroplasts and respiration in mitochondria. Whereas endomembrane system mainly involve in vesicle transport and they include the nuclear membrane, the endoplasmic reticulum, the Golgi apparatus, lysosomes, vesicles, endosomes and the cell membrane.
Answer:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids, ... Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth.
The methodology of simultaneous isolation of chloroplasts and mitochondria was first established for organelles from developing pea seedlings because this tissue is a widespread source of organelles utilized in protein transport assays.
