Question

What property of water is most important in allowing glucose to be dissolved in blood?

Answer 1

Water's polarity is the key property that allows glucose to dissolve in blood because it enables hydrophilic interactions between water molecules and glucose, facilitating its transport and utilization for energy in the body.

Step-by-step explanation:

The property of water that is most important in allowing glucose to be dissolved in blood is its polarity. Water molecules are polar, meaning they have regions with positive and negative electrical charge. This characteristic of water enables it to dissolve compounds that are hydrophilic, or 'water-loving,' such as glucose and other polar covalent compounds.

Glucose, being a polar molecule due to its hydrogen-oxygen polar bonds, interacts well with water. In the bloodstream, glucose is hydrophilic and readily dissolves, enabling it to be transported to cells where it can be utilized as a source of energy for various biochemical reactions, including glycolysis, which generates ATP for the body's energy needs.

Answer 2

The property of water which allows glucose to dissolve in blood is that water is an excellent solvent.

Step-by-step explanation:

The plasma is made up of 92% water. The polarity, as well as the formation of hydrogen bonds, makes water an excellent solvent. In an organisms body, materials like glucose, salts, ions etc are easily transported to areas where they are needed because the water content of plasma dissolves them and transports them. This is the reason why plasma which is 92% water constitute 55% of the total volume of blood.
