Question

the free ribosomes of mitochondria are present in its ( 1- matrix 2-inter membraneous space 3- outer membraneous space 4-on cristae of inner membrane ) which is correct

Answer 1

Answer:

The mitochondrion ( plural mitochondria) is a semi autonomous double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.To date, only one eukaryote, Monocercomonoides, is known to have completely lost its mitochondria,and one multicellular organism, Henneguya salminicola, is known to have retained mitochondrion-related organelles in association with a complete loss of their mitochondrial genome.
