Rainfall is as important as oxygen for the survival of all life forms. Why? Explain.
Answers
Answer:
is used because water is used for our oxygen survival
Answer:
Water as a Solvent
Water attracts both positive and negative ions, because of the nature of the chemical bonds in water. Thus, positive ions are attracted to the oxygen in water, while negative ions are attracted to the hydrogen. This allows water to dissolve compounds important for survival, such as glucose gleaned from ingesting food.
Water as a Temperature Buffer
Temperature regulation is vital for chemical reactions important to cellular activity, such as cellular respiration. Enzymes, or proteins that act as catalysts to start chemical reactions, are heat-sensitive and will operate only at specific temperatures.Water has a high specific heat capacity, meaning it takes a lot of heat to raise its temperature. Thus, water absorbs much heat without the temperature of the organism being raised. This prevents enzymes from becoming overheated and failing to function.raised. This prevents enzymes from becoming overheated and failing to function.
Water as a Metabolite
The sum total of chemical reactions within an organism is called metabolism. Water is a metabolite, or a chemical involved in reactions. In this way, it is is necessary for the continued survival of both plants and animals.
In plants, water aids in photosynthesis, the process by which plants convert sunlight into food. During the first stage of photosynthesis, water splits into hydrogen and oxygen atoms. Oxygen is released into the atmosphere, while hydrogen is used in the rest of the chemical reaction to produce glucose to feed the plant.
In animals, water aids in respiration. Water helps to split adenosine triphosphate (ATP) into adenosine diphosphate (ADP) and phosphoric acid. Cellular energy is released as a byproduct of this process. Water formation from oxygen and depleted hydrogen also moves waste products out of the body after the respiration cycle is complete.
