The Warburg Effect causes alterations in mitochondrial redox potential, ultimately changing ROS generation [18]. An important determinant of redox potential in cells is the NADH that is available in the mitochondria for electron transport.

The Reverse Warburg Effect describes when glycolysis in the cancer-associated stroma metabolically supports adjacent cancer cells. This catabolite transfer, which induces stromal-cancer metabolic coupling, allows cancer cells to generate ATP, increase proliferation, and reduce cell death.

In oncology, the Warburg effect is the observation that most cancer cells predominantly produce energy by a high rate of glycolysis followed by lactic acid fermentation in the cytosol, rather than by a comparatively low rate of glycolysis followed by oxidation of pyruvate in mitochondria as in most normal cells.

Five year survival by type

In plant physiology, the Warburg effect is the decrease in the rate of photosynthesis due to high oxygen concentrations. Oxygen is a competitive inhibitor of carbon dioxide fixation by RuBisCO which initiates photosynthesis. Furthermore, oxygen stimulates photorespiration which reduces photosynthetic output.

The (light) compensation point is the light intensity on the light curve where the rate of photosynthesis exactly matches the rate of cellular respiration. For instance, in the early morning and late evenings, the compensation point may be reached as photosynthetic activity decreases and respiration increases.

The metabolic pathway for photorespiration, in which sugars are oxidized to CO2 in the light, is known as the oxidative photosynthetic carbon cycle or C2 cycle. The term oxidative photosynthetic carbon cycle (C2 cycle) is used to be consistent with the term reductive photosynthetic carbon cycle, or C3 cycle.

So, the correct answer is ‘Synthesis of ATP’

Ribulose-1,5-bisphosphate carboxylase-oxygenase, commonly known by the abbreviations RuBisCo, rubisco, RuBPCase, or RuBPco, is an enzyme involved in the first major step of carbon fixation, a process by which the atmospheric carbon dioxide is converted by plants and other photosynthetic organisms to energy-rich …

The medulla oblongata is the primary respiratory control center. Its main function is to send signals to the muscles that control respiration to cause breathing to occur. There are two regions in the medulla that control respiration: The ventral respiratory group stimulates expiratory movements.

Difference between Light and Dark Reaction

Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.

The Light Reactions The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains. During the light reactions, water is used and oxygen is produced.

Essentially, oxygen is a waste product of the light reactions of photosynthesis. It is a ”leftover” from a necessary part of the process. All the oxygen that is necessary to maintain most forms of life just happens to come about during this process.

The endergonic (def) light-independent reactions of photosynthesis use the ATP and NADPH synthesized during the exergonic (def) light-dependent reactions to provide the energy for the synthesis of glucose and other organic molecules (def) from inorganic carbon dioxide and water.

As a byproduct of photosynthesis, oxygen gas is also released into the atmosphere through tiny openings in the leaves called stomata. The carbohydrates produced by photosynthesis provide us with an important energy source, while the oxygen is a critical component of the air we breathe.

The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air.

The greater the light intensity is, the oxygen production is also greater. The oxygen production begins to decrease at a light intensity of 37%. Temperatures between 17 and 31 degrees do not have an affect on oxygen production. When the temperature exceeds 31 degrees the production of oxygen decreases.

Experimental data showed that higher temperatures of operation produced samples with higher sugar concentration values, and also these samples reached their final concentration value in a quicker way.

ATP levels are found to vary inversely with temperature over the range (4″-37″C) studied, and this variation is found to be reversible. An indication of a possible direct correlation of ADP level with temperature was also obtained.

Air and Water Temperature Increases Lower levels of dissolved oxygen due to the inverse relationship that exists between dissolved oxygen and temperature. As the temperature of the water increases, dissolved oxygen levels decrease.

Cooler air is more dense than warmer air. Warm air can actually hold more moisture because molecules are farther apart, making more room for moisture. Cold air is dense and compact; it’s “thicker,” so when you breathe in you get more oxygen. They get more oxygen and it’s easier to cool their bodies.

As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.

If you mean air in general, both warm and cold have the same amount of oxygen. Warm air has less density of molecules. Thus, when you breathe in cool/cold weather, you are getting more oxygen into your lungs. Hot weather produces the feeling of “hard to breathe” due to the less amount of oxygen density.
