Cellular Respiration

Oxygen is produced during the light dependent reactions of photosynthesis in Photosystem II by the splitting of water, it is released into the air as O2.

This oxygen is then used in the first stage of cellular respiration glyciosis combining oxygen and glucose product. The oxygen generated in photosynthesis is needed for only for aerobic respiration. In cellular respiration, during the process of oxidation of pyruvate, a molecule of CO2 is released. Also during the Krebs cycle, two molecules of CO2 are released into the air. In the leaves of plants this CO2 is absorbed through small holes called the stomata.

The stomata open to absorb the carbon dioxide needed to perform photosynthesis. This CO2 is used in the light independent reactions of photosynthesis Calvin cycle. In photosynthesis, during the Calvin cycle some G3P molecules break off to produce glucose while others are reused in the Calvin cycle. The formed glucose is burned to release energy ATP during cellular respiration.

In cellular respiration, during the Krebs Cycle one molecule of H20 water is released when fumarate turns to malate. To a certain extent, these molecules can be used in photosynthesis. These water molecules end up in the thylakoid space and are passed through photosystem II providing a source of low energy electrons. The reaction center then splits water molecules and creates oxygen gas. Cellular respiration generates water, while photosynthesis consumes it.

O2 is not used during glycolysis, only during ox phos. You sort of made that point, by restricting it to aerobic respiration. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Log in or sign up in seconds. Submit a new text post.

Focus on functions of all the parts of mitochondria. Explain how hydrogen cyanide inhibits aerobic respiration. Your body begins processing ATP without the use of oxygen, which creates lactic acid as a byproduct.

If oxygen is present, the body is able to move the electrons along and complete ATP production via oxidative phosphorylation. If there is no oxygen present, glycolysis becomes the sole provider of ATP.

What book are you using? Are you just overwhelmed by the questions, do you genuinely not understand them, or are you just being a tad lazy? I can upload my biology notes on cellular respiration - they are old and the scans are a little wonky, but they might help. I really appreciate it. I think this is a q about the fact that electrons are getting passed down, stripped from the sugar. Since electrons can freely move, they are easier to pass down. This is not a complete answer and is a total guess.

How is bread making related to respiration? Plants take in sun and CO2. Stage 3 takes one molecule of glyceraldehyde-3 phosphate at a time and oxidizes them to pyruvate, which in turn generates ATP. In sum, one molecule of glucose generates the following: Keep in mind that although 4 ATP is the net amount generated by one molecule of glucose, the glycolytic pathway actually uses up 2 ATP during the conversion process.

Of this, glycolysis generates only 4 ATP. Comparably, glycolysis is just a small player in the bigger process of cellular respiration. So what happens to the pyruvate generated from glycolysis? If there is no oxygen present, it will be converted to lactate or ethanol by a process known as fermentation. Cellular respiration is the process by which our bodies harvest the energy stored in food.

It is how we get energy at the cellular level that allows our organs and tissues to function. Glycolysis begins with one molecule of glucose a 6-carbon molecule and results in two 3-carbon pyruvate molecules. The conversion creates energy in the form of ATP, or adenosine triphosphate.

AEROBIC RESPIRATION

Main Topics

Privacy Policy

Despite their similarities, photosynthesis and cellular respiration are distinct chemical reactions. Though the reactants of one process are the products of the other, the processes serve different functions and take place in different structures.

Privacy FAQs

The information on ANAEROBIC RESPIRATION (Fermentation) is incorrect. What you describe is fermentation, which is different from anaerobic respiration. Anaerobic respiration is basically the same as aerobic respiration, but alternative terminal electron accepts are used (in the absences of oxygen). It is almost as efficient as aerobic respiration.
