Question: Which Type Of Respiration Produces More ATP?

Is ATP produced in respiration?

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP.

The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation..

What type of respiration requires oxygen?

aerobicThere are two types of respiration: aerobic, which requires oxygen and releases lots of energy. anaerobic, which does not require oxygen but releases much less energy per mole of starting material.

What process produces ATP?

In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes—glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation—to produce ATP.

Why GTP is used instead of ATP?

The results showed that GTP:GDP ratio changed independently of the ATP:ADP ratio, and maybe that this the key. By having an independent supply of high energy phosphate, many cellular processes requiring energy are not tied to the ATP:ADP ratio. … So, nucleotides other than ATP are used for a variety reactions.

How are 32 ATP produced?

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.

How much ATP is produced in anaerobic respiration?

Without oxygen, organisms must use anaerobic respiration to produce ATP, and this process produces only two molecules of ATP per molecule of glucose.

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.

How do cells generate ATP in the absence of oxygen?

But, in the absence of oxygen, many cells generate ATP through glycolysis and fermentation. … Both types of fermentation regenerate oxidized NAD+, which is necessary for glycolysis and consequently the continued production of ATP by that pathway. The net energy gain in fermentation is 2 ATP molecules/glucose molecule.

What are examples of anaerobic respiration?

Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation (which can result in yogurt and in sore muscles), and in decomposition of organic matter. The equation is: glucose + enzymes = carbon dioxide + ethanol/lactic acid.

Which type of respiration is more efficient and why?

lecture15. Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration.

What are the two main types of anaerobic respiration?

Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.

What process requires oxygen?

Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.

How is 38 ATP formed?

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 oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

How are 36 ATP produced?

During respiration, 36 ATP molecules are produced per glucose molecule. 2 molecules of ATP are produced outside mitochondria i.e., during glycolysis and other 34 molecules of ATP are produced inside mitochondria from Krebs cycle.

What is the name of respiration that occurs in the absence of oxygen?

anaerobic respirationCellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.

Where does anaerobic respiration occur in human body?

Explanation: It is happening in places where mitochondria are not present. In humans, red blood corpuscles do not have mitochondria, that’s why anaerobic respiration always happens in RBCs. But in muscle cells, when there is a lack of oxygen, it happens as a result of the fact that lactic acid is produced.
