Which of the following is not required for anaerobic respiration?

Which of the following is not required for anaerobic respiration?

Unlike aerobic respiration, anaerobic respiration does not need oxygen. It is the release of a relatively small amount of energy in cells by the breakdown of food substances in the absence of oxygen.

Which of the following is true of anaerobic respiration?

Which of the following is true about anaerobic respiration? It is a very fast process, it allows organisms to live in places where there is little or no oxygen, and it evolved before aerobic respiration. It makes ATP without oxygen, and it involves glycolysis but not the other two stages of aerobic respiration.

Is NADH required for aerobic respiration?

In both aerobic and anaerobic respiration, the NADH molecule is part of the enzyme complex and must be restored to its NAD, oxidized state.

What are the two main steps of 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 are the two steps involved in breathing?

Answer. The two steps involved in breathing is inhalation and exhalation….

What are the two steps of respiration?

1. Breathing: Taking in air rich in oxygen (inhalation) and giving out air rich in carbon dioxide (exhalation) using respiratory system is called breathing. 2. Cellular Respiration: The process of breakdown of food in the cells with the release of energy is called cellular respiration….

What are the three steps which occur in the process of respiration?

Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate….

What are the five basic functions of the respiratory system?

There are five functions of the respiratory system.

  • Gas Exchange – oxygen and carbon dioxide.
  • Breathing – movement of air.
  • Sound Production.
  • Olfactory Assistance – sense of smell.
  • Protection – from dust and microbes entering body through mucus production, cilia, and coughing.

How do you describe the sequence of oxygen carbon dioxide and blood flow in your own words?

Answer Expert Verified The inhaled oxygen enters the lungs then oxygen reaches the alveoli. The inhaled oxygen passes quickly through the air-blood barrier going into the blood in the capillaries while carbon dioxide passes quickly from the blood going into the alveoli and then exhaled….

How are oxygen and carbon dioxide exchange in our body during respiration?

During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli….

What is the main function of gas exchange?

Gas exchange: The primary function of the lungs involving the transfer of oxygen from inhaled air into the blood and the transfer of carbon dioxide from the blood into the exhaled air.

What are the factors affecting gas exchange?

The main factors include:

  • Membrane thickness – the thinner the membrane, the faster the rate of diffusion.
  • Membrane surface area – the larger the surface area, the faster the rate of diffusion.
  • Pressure difference across the membrane.
  • Diffusion coefficient of the gas.

What is needed for efficient gas exchange?

Efficient gas exchange relies on a moist surface as oxygen must first dissolve into water before it can diffuse through a cell membrane.
