What is the main function of aerobic respiration?

Aerobic respiration provides energy to fuel all cellular processes. The reactions produce ATP, which is then used to power other life-sustaining functions, including growth, repair, and maintenance.

Which of the following is characteristic of anaerobic respiration?

(I) Aerobic respiration requires oxygen and mostly occurs in the mitochondria of a cell whereas anaerobic respiration does not require oxygen and takes place in the cell cytoplasm.

What are 4 characteristics of cellular respiration?

In eukaryotes, the 4 stages of cellular respiration include glycolysis, transition reaction (pyruvate oxidation), the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation through the electron transport chain.

What are the 3 major steps of aerobic respiration?

The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3).

What are the characteristics of an aerobic organism?

Aerobic organisms are organisms that need oxygen to make energy. Although some aerobic organisms, such as animals, breathe in oxygen through lungs or gills, other organisms, like plants, fungi, and bacteria, are also aerobic. All aerobic organisms use cellular respiration to make energy.

What are 5 differences between aerobic and anaerobic respiration?

Aerobic respiration takes place in presence of oxygen; whereas anaerobic respiration takes place in absence of oxygen. Carbon dioxide and water are the end products of aerobic respiration, while alcohol is the end product of anaerobic respiration. Aerobic respiration releases more energy than anaerobic respiration.

Which main events occur in aerobic respiration?

Aerobic respiration involves four stages: glycolysis, a transition reaction that forms acetyl coenzyme A, the citric acid (Krebs) cycle, and an electron transport chain and chemiosmosis.

What is the advantage of aerobic respiration?

A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.

What are the two types of aerobic respiration?

Name the different stages of Aerobic Respiration?
  • Glycolysis.
  • The Krebs cycle.
  • Oxidative phosphorylation.

How many ATP are produce by aerobic respiration?

38 ATP molecules
Theoretically, 38 ATP molecules can be produced by the complete oxidation of one glucose molecule in aerobic respiration.

Where do the reactions of anaerobic respiration occur?

While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

What are the two types of fermentation that occurs in anaerobic activity?

There are two types of fermentation, alcoholic and lactic acid. Fermentation follows glycolysis in the absence of oxygen. Alcoholic fermentation produces ethanol, carbon dioxide, and NAD+. Lactic acid fermentation produces lactic acid (lactate) and NAD+.

Which organisms most likely use anaerobic respiration?

What kinds of organisms use anaerobic cellular respiration? Some prokaryotes—bacteria and archaea—that live in low-oxygen environments rely on anaerobic respiration to break down fuels.

What is the advantage of aerobic respiration?

A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.

What is aerobic respiration example?

For instance, human beings undergo the process of respiration by inhaling oxygen gas and exhaling carbon dioxide gas. Many other living organisms including plants and animals undergo respiration process to obtain energy for their metabolic activities.

What enzyme is used in anaerobic respiration?

Anaerobic conditions in yeast convert pyruvate to carbon dioxide and ethanol. This occurs with the help of the enzyme pyruvate decarboxylase which removes a carbon dioxide molecule from the pyruvate to yield an acetaldehyde.

What are the advantages and disadvantages of aerobic respiration?

Advantages: Aerobic respiration generates a large amount of ATP. Disadvantages: Aerobic respiration is relatively slow and requires oxygen.
…
Muscle Metabolism
  • Within the muscle fiber. …
  • Creatine phosphate. …
  • Glucose stored within the cell. …
  • Glucose and fatty acids obtained from the bloodstream.

What is the main disadvantage of aerobic respiration?

Aerobic respiration produces a large amount of ATP as it uses oxygen to produce energy. Disadvantage of aerobic respiration is the process is slow and requires oxygen; without oxygen, energy cannot be converted.
