What biochemical pathways are involved in aerobic respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain. Glycolysis: Glucose ( 6 carbon atoms) is split into 2 molecules of glyceraldehyde phosphate (3 carbon each), then these are turned into pyruvate (3 carbons each).

What are the two pathways of aerobic respiration?

Electron Transport Chain. You have just read about two pathways in cellular respiration—glycolysis and the citric acid cycle—that generate ATP.

What is the biochemical pathway common to aerobic and anaerobic respiration?

Glycolysis. Glycolysis is a process common to both aerobic and anaerobic respiration.

What are the major pathways of anaerobic respiration?

Under anaerobic conditions, the absence of oxygen, pyruvic acid can be routed by the organism into one of three pathways: lactic acid fermentation, alcohol fermentation, or cellular (anaerobic) respiration.

What are the three biochemical pathways?

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain. Glycolysis is an anaerobic process, while the other two pathways are aerobic.

What three pathways are involved in respiration?

The metabolic pathway involved in respiration can be split into three main parts:

  • glycolysis – occurs in the cytoplasm.
  • citric acid cycle – occurs in the matrix of the mitochondria .
  • electron transport chain – occurs in the inner membrane of the mitochondria.

What are the 5 stages of aerobic respiration?

Overview of the steps of cellular respiration. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each)….

  • Glycolysis.
  • Pyruvate oxidation.
  • Citric acid cycle.
  • Oxidative phosphorylation.

Which of the following are the three main catabolic pathways of aerobic respiration?

Respiration has three key pathways: glycolysis, the citric acid cycle, and oxidative phosphorylation. Concept 9.1 Catabolic pathways yield energy by oxidizing organic fuels. Catabolic metabolic pathways release the energy stored in complex organic molecules. Electron transfer plays a major role in these pathways.

What is the pathway of respiration?

Respiratory System: Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)

What are the three metabolic pathways?

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain.

What is aerobic and anaerobic respiration?

Q7) Difference between aerobic and anaerobic respiration. Write the overall chemical equations of the two kinds of respiration in plants. Solution: Aerobic: Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy.

What are the two types of anaerobic respiration?

Two types of anaerobic respiration; Alcoholic Fermentation (yeast cells) and Lactic Acid Fermentation (higher animal muscle tissue during heavy activity).

What are the three processes of aerobic respiration?

Glycolysis

  • The Krebs cycle
  • Oxidative phosphorylation.

    What is the final step in aerobic respiration?

    The final step of aerobic respiration is the electron transport chain, or ETC. This last step uses the NADH and FADH2 that were created in previous steps to generate ATP. A lot of ATP, actually — 34 molecules of ATP to be exact.

    Why does aerobic respiration need oxygen?

    By definition, aerobic respiration requires oxygen. Oxygen is required because it is needed in the electron transport chain. The electron transport chain of a cell is a series of reactions that pair chemical reactions between electron donors and electron acceptors to the transfer of protons across a cellular membrane.

    What does aerobic respiration start with?

    Aerobic respiration is the process of producing cellular energy involving oxygen.The first step in is glycolysis , the second is the citric acid cycle and the third is the electron transport system. Anaerobic respiration is a type of respiration that does not use oxygen. as Aerobic respiration, it starts with glycolysis.
