Questions

Do anaerobic cells have a mitochondria?

Do anaerobic cells have a mitochondria?

They lack mitochondria which contain the oxidative phosphorylation pathway, which in all other animals combines oxygen with glucose to produce metabolic energy, and thus they consume no oxygen.

Are mitochondria involved in anaerobic respiration?

Anaerobic respiration (both glycolysis and fermentation) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the mitochondria.

Do anaerobic eukaryotes have a mitochondria?

Eukaryotes that use oxygen to optimize their energy production could not survive if their mitochondria were taken away. Since they have no mitochondria to complete aerobic respiration, all amitochondriate eukaryotes are anaerobic. Intestinal parasite Giardia lamblia, for example, is anaerobic and has no mitochondria.

What are mitochondria cells found in?

Mitochondria are found in the cells of nearly every eukaryotic organism, including plants and animals. Cells that require a lot of energy, such as muscle cells, can contain hundreds or thousands of mitochondria. A few types of cells, such as red blood cells, lack mitochondria entirely.

Are mitochondria found in prokaryotic cells?

Prokaryotes, on the other hand, don’t have mitochondria for energy production, so they must rely on their immediate environment to obtain usable energy. Prokaryotes generally use electron transport chains in their plasma membranes to provide much of their energy.

Was mitochondria its own cell?

A new study may have found an answer. Scientists think that mitochondria were once independent single-celled organisms until, more than a billion years ago, they were swallowed by larger cells. The nucleus now harbors the vast majority of the cell’s genetic material—even genes that help the mitochondria function.

Where in the mitochondria does the electron transport chain occur?

inner membrane
The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria.

Where in the mitochondria does aerobic respiration take place?

Mitochondria, organelles specialized to carry out aerobic respiration, contain an inner membrane folded into cristae, which form two separate compartments: the inner membrane space and the matrix. The Krebs Cycle takes place in the matrix.

Is mitochondria found in bacterial cells?

Prokaryotes, on the other hand, are single-celled organisms such as bacteria and archaea. Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus; instead their genetic material is free-floating within the cell. Thus, prokaryotes have no mitochondria.

Is mitochondria found in prokaryotic or eukaryotic cells?

Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus; instead their genetic material is free-floating within the cell. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria.

Are mitochondria found in all cells?

Mitochondria are found in all body cells, with the exception of a few. There are usually multiple mitochondria found in one cell, depending upon the function of that type of cell. Mitochondria are located in the cytoplasm of cells along with other organelles of the cell.
