Full Answer

How many ATP are made from glucose in a prokaryotic cell?

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.

How many ATP are produced in the citric acid cycle?

The citric acid cycle produces the equivalent of 2 ATP (it usually produces GTP, but that is ‘equivalent’ to ATP). 4. Oxidative phosphorylation — the electron transport chain followed by chemiosmosis — produces about 28 ATP.

Where is the respiratory chain located in prokaryotic cells?

In Prokaryotes, the respiratory chain and phosphorylation chain are located in the Plasma membrane. In prokaryotes and eukaryotes, some of the NADH is generated by the cytosolic Glycolysis. The oxidation of NADH is essentially not only to provide electrons for the electron transport chain but also to feed free NAD back to the glycolytic pathway.

How many ATP are produced by prokaryotes?

38 ATPsMost prokaryotes generate 38 ATPs from one glucose molecule.

Is ATP produced in prokaryotic cells?

Mitochondria, for example, are organelles that provide eukaryotes with most of their energy by producing energy-rich molecules called ATP. Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane.

How many ATP are produced in eukaryotes?

In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.

Why do we use 36 ATP instead of 38?

During citric acid cycle, 36 ATP molecules are produced. So, all together there are 38 molecules of ATP produced in aerobic respiration and 2 ATP are formed outside the mitochondria. Thus, option A is correct.

Why do eukaryotes only produce 36 ATP?

Why do eukaryotes generate only about 36 ATP per glucose in aerobic respiration but prokaryotes may generate about 38 ATP? eukaryotes must shuttle pyruvate across the mitochondrial membrane by active transport. prokaryotes possess an alternate to the Krebs cycle that generates more reduced electron. carriers.

How much ATP is produced in glycolysis in prokaryotes?

2 net ATPsIn prokaryotes the usual figure is 38. Per glucose, you get 2 net ATPs from glycolysis. A total of 10 NADH's is made (in glucolysis and the Krebs cycle) per glucose, and 2 FADH2's.

Where is the majority of ATP generated in prokaryotic cells?

Answer and Explanation: ATP is generated in the plasma membrane of prokaryotic cells.

How much ATP does aerobic respiration produce in prokaryotes?

38 ATP moleculesAltogether, 38 ATP molecules are produced during the process of cellular respiration in prokaryotes.

Do prokaryotes or eukaryotes make more ATP?

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.

Where is ATP made in eukaryotic cells?

mitochondriaIn a eukaryotic cell, biochemical activities are compartmentalized in small subcellular compartments call organelles. ATP, the energy currency of the cell, is made in an organelle called the "mitochondrium" (pl. "mitochondria").

How much ATP is produced in glycolysis in prokaryotes?

2 net ATPsIn prokaryotes the usual figure is 38. Per glucose, you get 2 net ATPs from glycolysis. A total of 10 NADH's is made (in glucolysis and the Krebs cycle) per glucose, and 2 FADH2's.

Where is the majority of ATP generated in prokaryotic cells?

Answer and Explanation: ATP is generated in the plasma membrane of prokaryotic cells.

How do prokaryotes produce energy without mitochondria?

Although prokaryotes lack mitochondria, energy production is still possible. ATP production occurs via electron transport in the cell membrane of t...

How many ATP are produced in cellular respiration in prokaryotes?

The net ATP production differs in aerobic and anaerobic cellular respiration. ATP yield is around 36-38 per glucose molecule in aerobic respiration...

Where does cellular respiration happen in prokaryotes?

Cellular respiration occurs in the cytoplasm and the cell membrane of prokaryotes. This is in contrast to eukaryotes, where most of the energy prod...

How is cellular respiration different in prokaryotes and eukaryotes?

Cellular respiration occurs in prokaryotes and eukaryotes in an almost similar fashion. Since prokaryotes lack mitochondria, the Krebs cycle and el...

How much ATP is produced during cellular respiration?

Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. ... Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

How many ATP are used in glycolysis?

9 steps occur to get to two molecules of pyruvate, and each are catalyzed by their own enzyme. 2 ATP are used to start the process, and 4 ATP are created, so their is a net gain of 2 ATP.

How many GTP molecules are produced in the Krebs cycle?

In other words - each glucose molecule is converted into 2 GTP molecules during Krebs cycle. GTP can be converted into an ATP as needed. That said, each cycle also produces 3 NADH and 1 FADH2, which sums up to 6 NADH molecules and 2 FADH2 molecules.

How many turns of the Calvin cycle are needed to make one molecule of glucose?

To make one molecule of glucose 6 turns of the cycle are required.

What are the steps of cellular respiration?

Cellular respiration occurs in three basic steps: glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain. In glycolysis, one 6-carbon molecule of glucose is broken down into two 3-carbon molecules of pyruvate. 9 steps occur to get to two molecules of pyruvate, and each are catalyzed by their own enzyme.

How many turns does acetyl CoA have?

One acetyl CoA leads to only 1 turn of the citric acid cycle. During 1 turn of the cycle, the equivalent of 1 ATP is produced by substrate-level phosphorylation (it is usually GTP that is produced, but 1 GTP is “equivalent to” 1 ATP).

What is the name of the 4-carbon molecule that combined with the acetyl group to make citrate?

Finally, malate is converted into oxaloacetate, the 4-carbon molecule that combined with the acetyl group to make citrate at the beginning of the cycle. During this time, NAD+ is reduced to NADH. This cycle produces 1 ATP, 3 NADH, and 1 FADH2 per acetyl CoA molecule.
