The number of membranes surrounding a mitochondria?

Answer 1

Two

Answer 2

A mitochondrion consists of outer and inner membranes, an intermembrane space (space in between the membranes), the cristae (infoldings of the inner membrane), and the matrix (space within the inner membrane).

Answer 3

The cytoplasm of nearly all eukaryotic cells contain mitochondria, although there is at least one exception, the protist Chaos (Pelomyxa) carolinensis. They are especially abundant in cells and parts of cells that are associated with active processes. For example, in flagellated protozoa or in mammalian sperm, mitochondria are concentrated around the base of the flagellum or flagella. In cardiac muscle, mitochondria surround the contractile elements. Hummingbird flight muscle is one of the richest sources of mitochondria known. Thus, from their distribution alone one would suspect that they are involved in energy production. Multicellular organisms probably could not exist without mitochondria. The inability to remove electrons from the system and the buildup of metabolic end products restrict the utility of anaerobic metabolism. Through oxidative phosphoryation mitochondria make efficient use of nutrient molecules. They are the reason that we need oxygen at all.

The double-membraned mitochondrion can be loosely described as a large wrinkled bag packed inside of a smaller, unwrinkled bag. The two membranes create distinct compartments within the organelle, and are themselves very different in structure and in function.

Answer 4

There are 2 membranes that surround mitochondrion. Any organelle that contains some kind of DNA has 2 membranes.

Answer 5

Two membranes.They are inner membrane and outer membrane.Inner membrane is highly folded

Answer 6

Two membranes- outer smooth and continuous and the inner one much folded in

to shelf like inward projections. The folds are called cristae.

Answer 7

There are two membranes.They are double membranous organells.

Answer 8

2 membranes.

Answer 9

two

Answer 10

Two
