Yes, most chemical reactions involved in metabolism do require water.
No, not all chemical reactions need water.
no
Endothermic reactions need heat.
Exothermic reactions are chemical rections since these affects the composition and chemical properties of a matter and result in the formation of new substance. Example burning of coal , electrolysis of water.
Many chemical reactions occur in water solutions. But a reaction can be realized also in solid or gaseous phase.
water
Cells need water to dissolve many of the chemical components of the cell. They need to have a precise range of concentration in order to function properly. They also need water in chemical reactions called hydrolysis reactions. In these reactions, chemical compounds are broken down by the addition of water.
to carry out chemical reactions they need to survive
Acid-Base Reactions.
It speeds up the chemical reactions so most reactions wouldn't happen without water.
Water is necessary for practically all activity needed to support life. All chemical reactions require water.
Because vital chemical reactions take place in water, and water is necessary to sustain life because of the important elements it has and the refreshment and nourishment it provides to organisms.
no
Endothermic reactions need heat.
Chemical reactions in the body take place in water.
Chemical reactions in the body take place in water.
chemical reactions are a big thing during our lives for instance.... if we didn't have water there will probably be no coke, just juice, oranges etc... thats why we need chemical reactions so that we have what we have today and what we use today such as electrical things etc...
