Question: How Are 32 ATP Produced?

Why is ATP 38 or 36?

Two processes take place during cellular respiration- glycolysis and krebs cycle.

In glycolysis, the glucose is broken down in the cytoplasm into pyruvate and 2 ATP.

In the mitochondrion, glucose is completely broken down into carbon dioxide and water and 36 ATP.

So total ATP produced is 38 ATP..

How are 36 ATP produced?

Electron transport system captures the energy of electrons to make ATP. … Total ATP production from aerobic respiration: 36 ATPs for each glucose that enters glycolysis (2 from glycolysis, 2 from citric acid cycle, 32 from ETP).

How many ATP does a 16 carbon fatty acid make?

129 ATPComplete oxidation of one palmitate molecule (fatty acid containing 16 carbons) generates 129 ATP molecules.

Why the number of ATP is not known exactly?

There are three reasons that we cannot state an exact number of ATP molecules generated by one molecule of glucose. Phosphorylation and the redox reactions are not directly coupled to each other, so the ratio of number of NADH to number of ATP is not a whole number.

How many ATP are formed in etc?

34 ATPElectron transport chain This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.

Why is the total count about 30 or 32 ATP?

Why is the total count of about 30 or 32 ATP molecules rather than a specific number? Organism that only carry out fermentation or anaerobic respiration, cannot survive in the presence of oxygen. Only creates two ATP for each molecule of glucose.

Which process produces the least amount of ATP?

Without oxygen, organisms can only break a 6-carbon glucose into two 3-carbon pyruvate molecules. As we saw earlier, glycolysis releases only enough energy to produce two (net) ATPs per molecule of glucose. In anaerobic respiration, this is where ATP production stops.

What is needed for ATP?

In order to make ATP, you need food (sugar) and oxygen. … You need oxygen to unlock the energy that’s in the food. Cellular respiration also explains why we are breathing oxygen and why we exhale carbon dioxide. In essence, the energy that was in covalent bonds of the glucose molecule is being released.

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? 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.

How is glucose converted to ATP?

Cells convert glucose to ATP in a process called cellular respiration. Cellular respiration: process of turning glucose into energy In the form of ATP. Before cellular respiration can begin, glucose must be refined into a form that is usable by the mitochondrion.

How many ATP can NADH make?

For every pair of electrons transported to the electron transport chain by a molecule of NADH, between 2 and 3 ATP are generated. For each pair of electrons transferred by FADH2, between 1 and 2 ATP are generated.

How many ATP is produced in glycolysis?

2 ATPDuring glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).

Do mitochondria create ATP?

Mitochondria are organelles – ‘small organs’ within each cell. They produce energy in the form of a molecule called ATP (adenosine triphosphate) which gets used throughout the cell to power the different jobs it has to do.

How do you calculate ATP production?

There is a theoretical maximum of 38 ATP produced from a single glucose molecule: 2 NADH produced in glycolysis (3 ATP each) + 8 NADH produced in Krebs cycle (3 ATP each) + 2 FADH2 produced I don’t know where (2 ATP each) + 2 ATP produced in the Krebs cycle + 2 ATP produced in glycolysis = 6 + 24 + 4 + 2 + 2 = 38 ATP, …

How do you get 38 ATP from glucose?

Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

What process produces 32 ATP?

In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.
