Solved by a verified expert:Water and LifeThe human body is about 70% water (not counting the water in body fat, which varies from person toperson). The body needs all this water to function normally. Just why is so much water required by humanbeings and other organisms? Water can dissolve many substances that organisms need, and it is necessaryfor many biochemical reactions. The examples below are among the most important biochemical processesthat occur in living things, but they are just two of many ways that water is involved in biochemicalreactions.• Photosynthesis — In this process, cells use the energy in sunlight to change carbon dioxide and waterto glucose and oxygen. The reactions of photosynthesis can be represented by the chemical equation6CO2 + 6H2O + Energy ? C6H12O6 + 6O2• Cellular respiration — In this process, cells break down glucose in the presence of oxygen and releasecarbon dioxide, water, and energy. The reactions of cellular respiration can be represented by thechemical equationC6H12O6 + 6O2 ? 6CO2 + 6H2O + EnergyWater is involved in many other biochemical reactions. As a result, just about all life processes depend onwater. Clearly, life as we know it could not exist without water.Questions1. Describe the best environment for the enzyme pepsin.2.
