What is the final electron acceptor during aerobic respiration?

To carry out aerobic respiration, a cell requires oxygen as the final electron acceptor.

Is oxygen the final acceptor?

Under aerobic growth conditions, the terminal electron acceptor is molecular oxygen. Terminal oxidases of aerobic respiratory chains of bacteria, which use O₂ as the final electron acceptor, can oxidize one of two alternative electron donors, either cytochrome c or quinol.

Which steps in aerobic respiration oxygen?

Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.

Does aerobic respiration require oxygen?

Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell.

What role does oxygen play in aerobic respiration?

Why oxygen? Oxygen is the final electron acceptor at the end of the electron transport chain of aerobic respiration. In the absence of oxygen, only a few ATP are produced from glucose. In the presence of oxygen, many more ATP are made.

Why is oxygen needed in aerobic respiration?

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 three end products of aerobic respiration?

End products of aerobic respiration are carbon dioxide, water and energy in the form of (38) ATP.

What are products of aerobic respiration?

Aerobic respiration makes two waste products:carbon dioxide and water.

How much oxygen is used in aerobic respiration?

Overall Equation. In summary, 1 molecule of six-carbon glucose and 6 molecules of oxygen are converted into 6 molecules of carbon dioxide, 6 molecules of water, and 38 molecules of ATP. The reactions of aerobic respiration can be broken down into four stages, described below.

What is a disadvantage of aerobic respiration?

Advantages: Aerobic respiration generates a large amount of ATP. Disadvantages: Aerobic respiration is relatively slow and requires oxygen.

What is the main 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.

Which stage is common to both aerobic and anaerobic respiration?

glycolysis

What is the advantage of aerobic respiration quizlet?

Advantages – aerobic is efficient, fermentation is fast, anaerobic requires no oxygen. Disadvantages – aerobic is slow, fermentation is inefficient, anaerobic produces bodily toxins (lactic acid, ethyl alcohol).

In which of the three main stages of aerobic cellular respiration is oxygen gas necessary quizlet?

oxygen & 3 stages: Glycolysis – Krebs Cycle – Electron Transport Chain. glycogen.

What is the main advantage of aerobic respiration of anaerobic respiration quizlet?

Compare aerobic and anaerobic respiration, and discuss the advantages of each. Aerobic respiration requires oxygen and produces far more ATP than anaerobic respiration, and anaerobic respiration does not require oxygen and allows survival in habitats which lack oxygen.

Where does aerobic respiration occur quizlet?

What is the aerobic cellular respiration? erobic respiration takes place in the presence of oxygen. It occurs in all plants, animals, and some prokaryotic organisms. The process involves a chemical reaction resulting into breakdown of energy molecules, obtained from carbohydrates (mainly glucose), proteins, and lipids.

What happens during aerobic respiration quizlet?

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. This results in a net gain of two ATP molecules. You just studied 9 terms!

What type of respiration takes place in the absence of oxygen?

Anaerobic respiration

What is the ultimate goal of cellular respiration?

Energy enters cellular respiration as stored energy in glucose. It leaves cellular respiration as ATP. The goal of cellular respiration is to provide energy to be used by the cell. Changing from glucose to ATP allows the energy in glucose to be used by the cell.

Where does oxygen end up in cellular respiration?

Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.

Which is the correct order of the four steps in aerobic cellular respiration?

Aerobic respiration has four stages: Glycolysis, formation of acetyl coenzyme A, the citric acid cycle, and the electron transport chain.

What is the correct order of the stages of cellular respiration quizlet?

The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs Cycle, and electron transport.

What is the correct sequence of events for aerobic respiration?

So, the correct answer is ‘Glycolysis, Krebs cycle, Electron transport chain’.

What is the pathway of electrons in cellular respiration?

In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is to capture this energy in the form of ATP.

What process does not release energy from glucose?

Photosynthesis does not release energy from glucose. Further Explanation: The cellular respiration is the process in which the substrate molecule gets broken down in a stepwise manner to release energy. The energy molecule is released in the form of ATP.
