Where is the electron transport chain located in prokaryotes?
the plasma membrane
In prokaryotes, the electron transport chain components are found in the plasma membrane. As the electrons travel through the chain, they go from a higher to a lower energy level, moving from less electron-hungry to more electron-hungry molecules.
How does cell transport in prokaryotic cells differ from cell transport in eukaryotic cells?
The small size of prokaryotes allows ions and organic molecules that enter them to quickly spread to other parts of the cell. Similarly, any wastes produced within a prokaryotic cell can quickly move out. However, larger eukaryotic cells have evolved different structural adaptations to enhance cellular transport.
Where does the electron transport chain take place in a eukaryotic cell?
inner mitochondrial membrane
In eukaryotic organisms the electron transport chain, and site of oxidative phosphorylation, is found on the inner mitochondrial membrane.
Which process occurs in the same location in prokaryotes and eukaryotes?
Transcription and Translation. These two processes are closely coupled in prokaryotes, whereas they are spacially and temporally separate in eukaryotes.
How does cellular respiration differ in prokaryotes and eukaryotes?
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.
How are prokaryotic and eukaryotic cells similar?
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.
Where does electron transport chain take place in the cell?
mitochondria
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
How does the location of translation differ between a prokaryote and a eukaryote?
In eukaryotes, transcription and translation take place in different cellular compartments: transcription takes place in the membrane-bounded nucleus, whereas translation takes place outside the nucleus in the cytoplasm. In prokaryotes, the two processes are closely coupled (Figure 28.15).
What is the difference between eukaryotic and prokaryotic translation?
The main difference between prokaryotic and eukaryotic translation is that prokaryotic translation is a simultaneous process with transcription whereas eukaryotic translation is a separate process from its transcription.
What are the 3 main differences between eukaryotic and prokaryotic cells?
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
What are the major differences between eukaryotic and prokaryotic translation?
Eukaryotic and Prokaryotic translations are involved in protein synthesis. The key difference between eukaryotic and prokaryotic translation is that eukaryotic translation and transcription is an asynchronous process whereas prokaryotic translation and transcription is a synchronous process.
Where does the electron transport chain occur in eukaryotes?
In Eukaryotes it occurs in inner membrane of mitochondria while in prokaryotes it occurs in cell plasma membrane.
Which is a model prokaryote for electron transport?
Paracoccus denitrificans is a gram-negative, facultative anaerobic soil bacterium. It is a model prokaryote for studies of respiration. When this bacterium grows aerobically, its electron transport chain possesses four complexes that correspond to the mitochondrial chain.
Where is the etc located in a prokaryote?
A membrane is required for the ETC to work, otherwise it would not be possible to build a gradient of hydrogen atoms. The only membrane in prokaryotes is the cellular membrane, that is where the ETC is located. On the top left corner the location of the ETC in prokaryotes, on the top right corner the situation in eukaryotes.
How are prokaryotes different from their eukaryotic counterparts?
Eukaryotes are then able to generate a proton gradient between the two mitochondrial membranes within the intermembrane space, while prokaryotes can generate a gradient between the cell membrane and cell wall. Prokaryotes and eukaryotes are defined by a series of differences.
