Proteins | Cell Walls | Connections | Cytoplasm | Nucleus Mitochondria are the working organelles that keep the cell full of energy. If a cell feels it is not getting enough energy to survive, more mitochondria can be Useful Reference Links. Tight coordination between the nucleus and mitochondria is required for the functional relationship between VDAC, the redox states of cell compartments ( e.g. J Cell Sci Suppl. ; Interaction between mitochondria and the nucleus.

Mitochondria Versus Nucleus

A mitochondrion has an outer membrane and an inner membrane. A nucleus also has an outer membrane and an inner membrane. The two membranes of a mitochondrion serve different purposes. The inner membrane is where energy molecules are made. For the nucleus, its outer membrane is connected to the endoplasmic reticulum, another membranous organelle.

The outer membrane of the nucleus also has ribosomes on it, similar to the rough endoplasmic reticulum. The inside of the inner nuclear membrane is held in place by a network of proteins that is like the wooden frame of a house.

Channels Control the Flow The two membranes in mitochondria and the nucleus are barriers separating things on the inside from things form the outside, but they have protein channels that allow molecules to move in and out.

The nucleus has what is called the nuclear pore complex, which is a protein channel that pokes through both the outer and inner membranes. This pore regulates what goes in and out.

The mitochondria have protein channels on the outer membrane that are right above protein channels on the inner membrane.

The outer channel passes proteins on the outside of the mitochondrion to the inner channel, which moves the protein to the inside of the mitochondrion. The main genome of the organism is found in the nucleus. In humans, the nucleus holds 46 chromosomes, which contains about 25, genes.

They are made of two membranes. The outer membrane covers the organelle and contains it like a skin.

The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle.

Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur. If you have more space to work, you can get more work done. Similar surface area strategies are used by microvilli in your intestines.

It's not like the movies at all. Mitochondria are special because they have their own ribosomes and DNA floating in the matrix.

There are also structures called granules which may control concentrations of ions. Cell biologists are still exploring the activity of granules. Using Oxygen to Release Energy How does cellular respiration occur in mitochondria?

The matrix is filled with water and proteins enzymes.
