What do the granules in mitochondria do?
Explanation: Mitochondrial matrix granules are particles containing phospholipids, proteins and calcium found in the mitochondria. They appear to create contact sites between inner and outer mitochondrial membranes in which enzymes can function efficiently.
What is the function of the intermembrane compartment of the mitochondria?
The intermembrane space, as implied, is the region between the inner and outer membranes. It has an important role in the primary function of mitochondria, which is oxidative phosphorylation. The matrix contains the enzymes that are responsible for the citric acid cycle reactions.
What are the main functions of the mitochondria?
​Mitochondria. 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).
What do ribosomes do in the mitochondria?
Mitochondrial ribosomes (mitoribosomes) perform protein synthesis inside mitochondria, the organelles responsible for energy conversion and adenosine triphosphate production in eukaryotic cells.
What are the folds of mitochondria called?
Each mitochondrion has two membranes: an inner membrane which is highly convoluted and folded into finger-like projections called cristae, and a smooth outer membrane that is a selective barrier to molecules from the cytoplasm.
Which of the following organisms lacks mitochondria?
A few types of cells, such as red blood cells, lack mitochondria entirely. As prokaryotic organisms, bacteria and archaea do not have mitochondria.
What happens if mitochondria not function?
If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.
Which of the following is not part of the cytosol?
Membrane-bound organelles float in the cytosol, but their interiors are not considered to be part of it. Chloroplasts, mitochondria, nuclei, and other closed, self-contained membranes within cells have their own internal fluid and chemistry that is separate from the cytosol.
