How does a prokaryotic cell get ATP if it does not have a mitochondria?

How does a prokaryotic cell get ATP if it does not have a mitochondria?

Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane. The thinking is that producing ATP on dedicated membranes inside the cell, rather than on the cell surface, boosted the amount of energy available to eukaryotic cells and allowed them to diversify more.

How do prokaryotes obtain energy for cellular respiration?

Some prokaryotes are heterotrophic. These prokaryotes must consume organic compounds in order to obtain energy. Prokaryotes do not have mitochondria to convert the organic compounds into ATP via cellular respiration. Instead, prokaryotes utilize enzymes that are attached to their cell membranes to produce ATP.

How do prokaryotic cells carry out the function of the mitochondria?

One point was earned for describing how prokaryotes carry out the function of mitochondria, by stating that “their electron transport chain is located in the plasma membrane.” One point was earned for describing how prokaryotes carry out the function of chloroplasts, by stating, “For sugar synthesis, the prokaryotes …

Why do prokaryotic cells produce more ATP than eukaryotic cells?

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.

Which of the following are ways of obtaining energy for prokaryotic organisms?

The Ways in Which Prokaryotes Obtain Energy Prokaryotes can use different sources of energy to assemble macromolecules from smaller molecules. Phototrophs (or phototrophic organisms) obtain their energy from sunlight. Chemotrophs (or chemosynthetic organisms) obtain their energy from chemical compounds.

Why do prokaryotes produce more ATP than eukaryotes?

Do prokaryotic cells have mitochondria?

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.

What might happen if a cell didn’t have any ATP?

Since ATP is the energy source of cells, it is an essential element in the machinery of the entire system. Without energy, some of the processes in the cell like active transport, cellular respiration, electron transport chain, and other cellular processes which include ATP as pre-requisite, would not work.
