The major food molecule in living organisms is a sugar called glucose. Most carbohydrates (sugars and starches) are converted into glucose before they are broken down in the cytosol to release energy. The series of steps where glucose is broken down to release energy begins with a metabolic pathway called glycolysis. Glycolysis is the "lysing" or cutting of glucose to release energy. The six carbon sugar, glucose, is cut in half and converted into two three carbon sugars called pyruvate. What happens next depends on the presence or absence of oxygen.
If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation. Fermentation doesn't break the sugar down any further, it simply helps reset the system so that more sugar can be broken down.
Because aerobic respiration breaks the sugar all the way down, it releases much more energy than fermentation.
Answer:
It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. Plants need to cool themselves for several reasons. ... Transpiration is an evaporative cooling system that brings down the temperature of plants, but since it leads to water loss, it must be accurately regulated.
Explanation:
The answer to your question is Mutualism.
The correct answer is sympathetic nervous system.
In the given case, the harry is experiencing stress, which provokes the flight and fight syndrome. The sympathetic nervous system causes the release of adrenaline and noradrenaline causing change in physiological responses. During the flight and fight response, a hyperarousal occurs, which leads to the change in physiological responses. It causes the increased heart beat, increased blood pressure, anxiety, increase in pulse, increased sweating etc.
