In terms of the gas taken in and the gas given out, photosynthesis is the opposite of respiration. How does photosynthesis and respiration work together to How does photosynthesis and respiration work together to recycle the carbon dioxide and oxygen in the biosphere? Photosynthesis and Cellular Respiration - Jobworks Biology Cells, Mitosis-Meiosis, Photosynthesis-Cellular Respiration Notes C The two processes also work together to recycle oxygen in Earth's atmosphere. Cellular Respiration/Photosynthesis Test Study Guide Cellular respiration requires oxygen and Coenzymes and ATP Recycle a.

Photosynthesis-cellular respiration recycle oxygen Explain how the metabolic processes of cellular respirationand photosynthesis recycle oxygen. Trace a molecule of O2 from the environment to a musclecell in a UCSB Science Line Plants actually hold on to a small amount of the oxygen they produced in photosynthesis and use that oxygen to break down This is cellular respiration.
Some organic molecules of food provide the carbon skeletons or raw materials for the synthesis of new macromolecules. Some organic monomers from digestion can be used directly in anabolic pathways, other precursors come from glycolysis or Krebs cycle intermediates which are diverted into anabolic pathways. These anabolic pathways consume ATP produced by catabolic pathways of glycolysis and respiration. In response to the cell’s metabolic demands, Glycolysis and Krebs cycle can convert one type of macromolecule to another.Cells respond to changing metabolic needs by controlling reaction rates. The most common mechanism of control is feedback inhibition. Catabolic pathways, such as glycolysis and Krebs cycle, are controlled by regulating enzyme activity at strategic points. The ratio of ATP to ADP and AMP reflects the energy status of the cell, and phosphofructokinase is sensitive to changes in this ratio. Citrate (produced in Krebs cycle) and ATP are allosteric inhibitors of phosphofructokinase, so when their concentrations rise, the enzyme slows glycolysis. As the rate of glycolysis slows, Krebs cycle also slows since the supply of acetyl CoA is reduced. This synchronizes the rates of glycolysis and Krebs cycle. ADP and AMP are allosteric activators for phosphofructokinase, so when their concentrations relative to ATP rise, the enzyme speeds up glycolysis which speeds up the Krebs cycle. In summary, Glycolysis produces a net of 2 ATP per glucose molecule. Without oxygen, glycolysis is part of fermentation that regenerates NAD+, the oxidizing agent for glycolysis. In alcohol fermentation, pyruvate is converted into acetaldehyde, and CO2 is released. Acetaldehyde is then reduced by NADH to form ethanol (ethyl alcohol), and NAD+ is regenerated. In lactic acid fermentation, pyruvate is reduced to form lactate and recycle NAD+; no CO2 is released. Muscle cells make ATP by lactic acid fermentation when energy demand is high and oxygen supply is low. Comparison of Fermentation and Respiration. Both fermentation and respiration use glycolysis with as the oxidizing agent to convert glucose and other organic fuels to pyruvate. To oxidize fermentation uses pyruvate or acetaldehyde as the final electron acceptor, whereas respiration uses oxygen via the ETC. Also, with oxygen available, pyruvate can be oxidized in the Krebs cycle to produce much more ATP. Facultative anaerobes, such as yeast and some bacteria, can make ATP by fermentation or respiration, depending upon whether oxygen is available. Glycolysis is common to fermentation and respiration. This most widespread of all metabolic processes, occurs in the cytosol of prokaryotes and eukaryotes) probably evolved in ancient prokaryotes before oxygen was available.Glycolysis and the Krebs cycle connect to many other metabolic pathways.The Versatility of Catabolism. Fats, proteins, and carbohydrates can all be used by cellular respiration to make ATP. Proteins are digested into amino acids, which are then deaminated and can enter into respiration at several sites. The digestion of fats yields glycerol, which is converted to an intermediate of glycolysis, and fatty acids, which are broken down by beta oxidation to two-carbon fragments that enter the Krebs cycle as acetyl CoA. Feedback mechanisms control cellular respiration. Through feedback inhibition, the end product of a pathway inhibits the enzyme that initiates the pathway, thus preventing a cell from producing an excess of a particular substance. The supply of ATP in the cell regulates respiration. The allosteric enzyme that catalyzes an early step of glycolysis, phosphofructokinase, is inhibited by ATP and activated by ADP. Phosphofructokinase is also inhibited by citrate transported from the mitochondria into the cytosol, thus synchronizing the rates of glycolysis and the Krebs cycle. Other enzymes located at key intersections help to maintain metabolic balance.
