What is the correct sequence of steps in respiration when oxygen is present?

Ch. 9 Honors Biology Cellular Respiration

What is the step by step process of respiration?

There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation. During glycolysis, glucose molecules (six-carbon molecules) are split into two pyruvates (three-carbon molecules) during a sequence of enzyme-controlled reactions. This occurs in both aerobic and anaerobic respiration.

What is the process of oxygen in cellular respiration?

The Electron Transport Chain Stage three of cellular respiration is the use of NADH and FADH2 to generate ATP. This occurs in two parts. First, the NADH and FADH2 enter an electron transport chain, where their energy is used to pump, by active transport, protons (H+) into the intermembrane space of mitochondria.

What are the 7 steps of cellular respiration in order?

What is the sequence during cellular respiration?

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

Which of the following is the correct sequence of stages in cellular respiration quizlet?

What is the correct sequence of steps in cellular respiration, starting with glucose? Glycolysis, pyruvate processing, citric acid cycle, electron transport, oxidative phosphorylation.

What are the 4 phases of respiration?

The respiratory cycle is divided into 4 phases: inspiration (light green), end-inspiration (dark green), expiration (light red) and end-expiration (dark red).

What are the 5 phases of respiration?

Exchange of gases between air and blood at pulmonary capillaries (Alveoli)….Terms in this set (5)

• Pulmonary Ventilation.
• External Respiration.
• Transport of gases through blood vessels.
• Internal Respiration.
• Cellular Respiration.

What are the 3 steps in respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.

In which phase of cellular respiration is oxygen a substrate?

electron transport 11
In which phase of cellular respiration is oxygen a substrate? The electron transport 11.

What is the role of oxygen in aerobic cellular respiration?

Explanation: Oxygen is the final electron acceptor in aerobic respiration. Without the presence of oxygen, electrons would remain trapped and bound in the final step of the electron transport chain, preventing further reaction. NADH and FADH2 are necessary to donate electrons to the electron transport chain.

What are the four stages of respiration of oxygen?

Air-breathing of humans, respiration of oxygen includes four stages: Ventilation from the ambient air into the alveoli of the lung. Pulmonary gas exchange from the alveoli into the pulmonary capillaries.

What is the role of oxygen in cellular respiration?

Oxygen plays an essential role in energy production in the cell through a system called the electron transport chain (ETC), which is an important component of cellular respiration. Cellular respiration is the process that all cells use to make energy. Does cellular respiration require oxygen?

What is the gas exchange process in the respiratory system?

The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled. In the throat, the trachea, or windpipe, filters the air.

What happens in the last step of cellular respiration?

The last step of cellular respiration is where oxygen comes in. During oxidative phosphorylation, all of the electron carriers generated in the previous steps bring the electrons to the inner mitochondrial membrane. Here, the electrons can be passed between proteins embedded in the membrane, called the electron transport chain.
