Is cellular respiration more efficient in eukaryotes or prokaryotes?

Is cellular respiration more efficient in eukaryotes or prokaryotes?

Cellular respiration in eukaryotes is slightly more efficient than in prokaryotes. The Krebs cycle is sometimes called the TCA cycle or the citric acid cycle. The two pyruvate molecules formed during glycolysis result in two Krebs cycles.

How would cellular respiration differ between eukaryotic and prokaryotic cells?

Both eukaryotic and prokaryotic organisms get the energy they need to grow and maintain normal cellular function through cellular respiration. In eukaryotes, most cellular respiration reactions take place within the mitochondria. In prokaryotes, they occur in the cytoplasm and/or within the cell membrane.

Do prokaryotic cells do respiration?

Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. The energy currency of these cells is ATP, and one way to view the outcome of cellular respiration is as a production process for ATP.

Why do prokaryotes not use cellular respiration?

In your cells, cellular respiration happens in a special organelle called the mitochondrion. But as mentioned, prokaryotic organisms don’t have organelles. Rather than taking place in the mitochondrion, cellular respiration happens either in the cytoplasm or across the plasma membrane of the cell.

Where does cellular respiration take place in eukaryotes How about in prokaryotes?

Cellular respiration location In prokaryotic cells, it is carried out in the cell cytoplasm, in eukaryotic cells it begins in the cytosol then is carried out in the mitochondria.

Are prokaryotic cells aerobic or anaerobic?

Many prokaryotes are facultatively anaerobic. This means that they can switch between aerobic respiration and fermentation, depending on the availability of oxygen. Certain prokaryotes, like Clostridia bacteria, are obligate anaerobes.

Why do prokaryotes make more ATP than eukaryotes?

Complete answer: In prokaryotes, there are no mitochondria, the whole process of respiration occurs within the cytoplasm so no ATP is consumed in transporting across the organelle. Therefore, 38 ATPs are made from one glucose in bacteria while 36 are made in a eukaryotic cell.

Are prokaryotes larger than eukaryotes?

Eukaryotic cells are generally bigger — up to 10 times bigger, on average, than prokaryotes. Their cells also hold much more DNA than prokaryotic cells do.

Where does respiration take place in eukaryotic cells?

mitochondria
In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into mitochondria, which are the sites of cellular respiration.

Why can only eukaryotes do aerobic respiration?

The energy yield from anaerobic respiration is not as good as the yield from aerobic respiration. For this reason, eukaryotes always use aerobic cellular respiration when oxygen is available to them.

Does aerobic cellular respiration happen in prokaryotic organisms if yes where?

Does aerobic cellular respiration happen in prokaryotic organisms- if yes- where? No, aerobic cellular respiration does not happen in prokaryotes because they do not have membrane organelles. Like mitochondria, which are required for the citric acid cycle. Ancient prokaryotes probably used it before oxygen was present.

Why do eukaryotes have less ATP?

Why do eukaryotes generate only about 36 ATP per glucose in aerobic respiration but prokaryotes may generate about 38 ATP? A) eukaryotes have a less efficient electron transport system. eukaryotes do not transport as much hydrogen across the mitochondrial membrane as prokaryotes do across the cytoplasmic membrane.
