Question

Water is the most abundant molecule found in living organisms. Most mammals, in fact, are approximately 70% water by weight. About two-thirds of this water is present inside cells. The other one-third is present outside cells (e.g., in blood plasma or other body fluids). Why is water so important to cells?

Water determines which proteins are translated from the cellular DNA.

Water is stored in the cells to be used when the organism gets thirsty.

Almost all the chemical reactions in life processes occur in solutions with water.

Answer 1

Almost all the chemical reactions in life processes occur in solutions with water.

Answer 2

if the cell lacks water it will shrink and get dehydrated. our body is made up of cells,therefore if cells gets dehydrated our body gets dehydrated as well,and it could lead to death. so it is the Almost all the chemical reactions in life processes occur in solutions with water.

Answer 3

Water is the medium in which everything is suspended. If you don't have enough of it, then cellular components cannot move around in the way they're supposed to, and therefore can no longer perform their function properly.

If you've studied enyzmes in any capacity, then you'll know that they need to collide with substrates in order to make any reaction happen. If the cell gets too congested, then the range of motion of all of these proteins and enzymes is severely hampered, and it's less likely the right things will collide together. This will slow down everything in the cell, until it becomes so dehydrated that it essentially becomes a solid mass. Then it doesn't work at all. Almost all the chemical reactions in life processes occur in solutions with water.

Answer 4

Almost all the chemical reactions in life processes occur in solutions with water.
