Often asked: Which Two Metabolic Processes Are Paired With Respect To Carbon Cycling And Energy Flow?


What are the 2 pathways that might follow glycolysis?

Cellular Respiration: Glycolysis is the first pathway of cellular respiration that oxidizes glucose molecules. It is followed by the Krebs cycle and oxidative phosphorylation to produce ATP.

What two stages of cellular respiration produce the carbon dioxide you exhale?

Krebs cycle (or Citric acid cycle) This breaks down the pyruvic acid to carbon dioxide. This produces 2 ATP and 6 NADH, for every glucose molecule entering glycolysis. The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out.

What are the steps of cellular respiration?

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

What is the final electron acceptor in the electron transport chain of aerobic respiration quizlet?

Aerobic respiration uses oxygen as its final electron acceptor at the end of the electron transport chain.

What is the net gain of ATP for glycolysis?

In glycolysis, the net gain of ATP molecules is 2. Two ATP per glucose molecule are required to initiate the process, then a total of four ATP are produced per molecule of glucose.

Why is glycolysis not efficient?

During glycolysis, two NADH molecules are produced. Because glycolysis does not require oxygen, the process is considered to be anaerobic. Glycolysis is a somewhat inefficient process because much of the cellular energy remains in the two molecules of pyruvic acid that are created.

Which process does not release energy from glucose?

Photosynthesis does not release energy from glucose.

At what phase would cellular respiration come to a halt without B1?

Vitamin B1 has to be taken in through the diet of an individual. At what phase would cellular respiration come to a halt without B1? the removal of electrons and hydrogen from glucose.

What is the end product of the Preparatory reaction?

the product of the preparatory reaction. in the preparatory reaction, two pyruvate molecules are converted to acetyl-groups and CO2. the two-carbon acetyl-groups are then carried into the citric acid cycle in the mitochondrial matrix by a molecule called CoA.

What are the three metabolic processes of cellular respiration?

The overall process, however, can be distilled into three main metabolic stages or steps: glycolysis, the tricarboxylic acid cycle (TCA cycle), and oxidative phosphorylation (respiratory-chain phosphorylation).

What is the correct order for the three steps of aerobic respiration?

Answer: The correct answer is- 1) Glycolysis, 2) Kreb cycle, 3) Electron transport chain. Cellular respiration is a process of oxidation of food molecule ( like glucose) so as to form carbon dioxide, water, and large amount of energy in the form of ATP ( adenosine triphosphate).

What is process of respiration?

“ Respiration is defined as a metabolic process wherein, the living cells of an organism obtains energy (in the form of ATP) by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.”

Which type of respiration uses nitrate as a final acceptor quizlet?

-In anaerobic respiration, the final electron acceptor is an inorganic substance other than oxygen, such as nitrate, sulfate, or carbonate.

What is the final electron acceptor of aerobic cellular respiration?

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

Why does lack of oxygen result in the halt of ATP synthesis?

Why does lack of oxygen result in the halt of ATP synthesis? The chain shuts down and can no longer pump hydrogen ions across the membrane, and the proton gradient cannot be maintained. This causes the proton gradient to break down, stopping ATP synthesis.
