The human body is about 70% water not counting the water in body fat, which varies from person to person. The body needs all this water to function normally. Just why is so much water required by human beings and other organism? Water can dissolve many substances that organisms need, and it is necessary for many biochemical reactions. The examples below are among the most important biochemical processes that occur in living things, but they are just two of many ways that water is involved in biochemical reactions. Photosynthesis in this process, cells use the energy is sunlight be change dioxide and water to glucose and oxygen. The reactions of photosynthesis can be represented by the chemical equation. 6CO_2 + 6H_2O + Energy rightarrow C_6H_12O_2 + 6O_2 Cellular respiration In this process, cells break down glucose in the presence of oxygen and release carbon dioxide, water, and energy. The reactions of cellular respiration can be represented by the chemical equation C_6H_12O_2 + 6O_2 rightarrow 6CO_2 + 6H_2O + Energy Water is involved in many other biochemical reactions. As a result, just about all life processes depend on water. Clearly, life as we know it could not exist without water. Describe the best environment for the enzyme pepsin. Why is water so important for life?

Solution

The best environment for pepsin is very acidic due to hydrochloric acid as it is found in stomach I would assume the best environment for pepsin would be an acid-rich environment.

Water is best solvent in nature which is non toxic so it is important because living systems require solvents in order to mix various chemicals with one another.

citric acid in present in the case of lemon juice that is very weak acid so may be pep soda is stronger than first
