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.
Where do the 4 stages of respiration occur?
Glycolysis takes place in the cell cytoplasm. The Link reaction takes place in the matrix of the mitochondria. The Krebs cycle takes place in the matrix of the mitochondria. Oxidative phosphorylation occurs at the inner membrane of the mitochondria.
What is the correct order of phases in cellular respiration quizlet?
The order of phases in cellular respiration is glycolysis, prep reaction, citric acid cycle, and electron transport chain.
Which stage of the 4 stages of cellular respiration is the anaerobic stage?
Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen.
What are the 4 stages of cellular respiration explained Related Questions
Which of the four phases of cellular respiration produce?
Which of the four phases of cellular respiration produce water? Oxidative phosphorylation. 4. The goal of cellular respiration is to provide the cell with energy in the form of ATP.
What are the four 4 aspects of respiration?
Breathing. The body brings air to the lungs by contracting the diaphragm. Gas Exchange Between Air and Blood in Lungs (Pulmonary Gas Exchange) Gas Transport. Gas Exchange Between Blood and Tissues (Peripheral Gas Exchange)
What is in the first step of cellular respiration called?
Glycolysis is the first step in cellular respiration that occurs in the cytoplasm within the mitochondria. Glycolysis is the process in which glucose six-carbon sugar molecule is broken down into 3C molecules to generate cellular energy.
What are the steps of cellular respiration in which carbon dioxide is formed?
The molecules of carbon dioxide are produced in the second stage of cellular respiration, that is, in the Krebs cycle. These molecules of carbon dioxide are carried by the circulating blood to the alveolar tissues; from there, it is expelled out of the body via a breathing mechanism.
What is step 4 of 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 process of the respiration?
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
What is the correct order of the steps of energy production?
So, the correct answer is ‘Carbohydrates ‚Üí Glycolysis ‚Üí Pyruvic acid ‚Üí AcetylCoA ‚Üí Krebs cycle ‚Üí CO2 + H2O + energy’.
What are the 4 main products of cellular respiration?
The products of cellular respiration are carbon dioxide, ATP, and water. During the production of acetyl-CoA from pyruvate, two carbon dioxide are formed. An additional four carbon dioxide are formed during the Krebs cycle.
Which of the 4 steps of cellular respiration produces the most energy via oxidative phosphorylation?
Oxidative phosphorylation is the fourth step of cellular respiration, and produces the most of the energy in cellular respiration.
What are the first 4 parts of the respiratory system?
Voice box (larynx) Windpipe (trachea) Airways (bronchi) Lungs.
What is the last step in cellular respiration?
Answer and Explanation: The last stage of cell respiration that links to the Krebs cycle is the electron transport chain (ETC) & oxidative phosphorylation.
What is the 2nd step of cellular respiration?
The second step in cellular respiration is called the Krebs cycle. The Krebs cycle uses pyruvic acid to create ATP, along with additional molecules like NADH, FADH2, and CO2. The NADH and FADH2 molecules are used during the final step of cellular respiration, while the CO2 is exhaled.
What are the three stages of the cellular respiration?
Stages of Cellular 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).
Which of the following statement about cellular respiration is true?
Answer and Explanation: The correct answer C. You can obtain energy from both proteins and fat even though the initial energy expenditure is much. The preferred molecule that cells will use to generate energy is glucose.
Which process of cellular respiration takes place in the cytoplasm?
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 happens during step 3 of aerobic respiration?
The third and final stage of cellular respiration, called electron transport , takes place on the inner membrane of the mitochondrion. Electrons are transported from molecule to molecule down an electron-transport chain.
