Which liberates the most energy in the form of atp
A portion of a DNA molecules wound around a spool of histone protein is called a In eukaryotic cells, which can occur during the stages of mitosis? The chromatids detach from one another and become visibly separate chromosomes during. The distribution of cytoplasm to daughter cells is accomplished during.
Four of the five answers listed below are events occurring during mitosis. Select the exception. Different, or alternative, forms of the same gene are called. Chromosomes of a pair of homologous chromosomes may differ from other chromosomes in terms of Four of the five answers listed below are related to pairing of chromosomes. A l oss of e lectrons is o xidation, while a g ain of e lectrons is r eduction. To produce the high energy electron carriers and. To produce from the high energy electron carriers and.
To produce through substrate level phosphorylation. During oxidative phosphorylation, is created from the previously created and. All of the other choices describe other parts of cellular respiration. In glycolysis, glucose is oxidized to pyruvate. In both glycolysis and the Krebs cycle, substrate level phosphorylation occurs.
Likewise, and are produced during glycolysis and the Krebs cycle, but not during oxidative phosphorylation, where these high energy electrons are passed down a series of membrane-bound enzymes to oxygen meanwhile protons are pumped into the intermembrane space of the mitochondria.
Which of the following steps represents a correct source of carbon dioxide during aerobic respiration? To answer this question, it's important to have familiarity with the process of aerobic respiration. In the first major pathway, glycolysis is split into two molecules of pyruvate through a series of reactions.
Along the way, high-energy electron carriers are produced, along with ATP. In the next major step, pyruvate is transferred into mitochondria, where it is decarboxylated into acetyl-CoA, with a concomitant production of NADH and carbon dioxide.
Hence, this is a step that produces carbon dioxide. However, it is not found in the answer choices. The third major component of aerobic respiration is the citric acid cycle. Here, the acetyl-CoA from the previous step is completely ripped apart to provide a great deal of energy.
This huge amount of energy that is liberated is because the two carbon atoms that make up the acetyl group of acetyl-CoA become completely oxidized into two molecules of carbon dioxide. In terms of the energy liberated from the cycle, ATP along with a good deal of high-energy electron carriers are produced.
This component of aerobic respiration is indeed a source of carbon dioxide. Fermentation is an anaerobic pathway and is thus not the correct answer.
Depending on the organism, carbon dioxide may or may not be produced. Finally, aerobic respiration culminates in oxidative phosphorylation. Here, all of the high energy carriers from the previous steps are fed into the electron transport chain, resulting in the production of a great amount of ATP, the main energy currency of cells.
In this final major step, it is oxygen gas that is produced, not carbon dioxide. If you've found an issue with this question, please let us know.

Hanley Rd, Suite St. Louis, MO Subject optional. Email address: Your name:. Possible Answers: None of these. Correct answer: All of these. Explanation : Reactive oxygen species are superoxide, hydrogen peroxide, and hydrogen radicals.
Report an Error. Which of the following are uncouplers of the electron transport chain? Carbon monoxide II. Nitric oxide IV. Correct answer: II and IV. Explanation : Uncouplers of the electron transport chain decrease the proton gradient and thus decrease ATP synthesis.
What is an electron acceptor in oxidative phosporylation? Possible Answers: Carbon monoxide. Your brain contains many nerve cells that need lots of ATP. Your liver is the largest organ in your body. Its cells take up glucose from your blood and convert it to glycogen for short-term storage recall that glycogen is a form of starch made by animals. Muscle cells also take up blood glucose. Some is used to make ATP for muscle contraction. The excess is converted to glycogen for storage. Adipose tissue is composed of fat cells.
They can take up excess blood glucose and convert it into long fatty acid molecules. Two or three of these combine to produce a fat molecule. Accumulated fats look like large oily droplets in fat cells. Fats and oils in your food are converted to fatty acids by enzymes in your intestine and taken up by your blood there.
Since there is already glucose in the blood after a meal, the fatty acids are taken up by the fat cells in adipose tissue and converted to fats for storage. Proteins in your food are broken up into their component amino acids by enzymes and hydrochloric acid in your stomach. The amino acids are taken up by your blood in your intestine. All cells can take up amino acids from the blood to make new proteins.
Most of your body's protein is in muscle cells, which contain large amounts of cytoskeleton and motor proteins for contraction. Muscles consume lots of amino acids if they are growing. Amino acids in the blood are also taken up by the liver and converted into glycogen. This entails a little extra processing. Glycogen is a carbohydrate. To convert amino acids to carbohydrates, the amino groups must be removed.
Free amino groups are NH 3 ammonia , which is toxic to cells. Cells in your liver convert NH 3 to urea, which is less toxic than ammonia, and load it into your blood.
