Why is glucose so versatile?
This versatile molecule then plays many roles in the life of the plant – and the lives of animals that eat them.
A primary role for the glucose molecule is to act as a source of energy; a fuel.
Very often the addition of one or more sugar molecules will make the recipient molecule more soluble..
Is crystallization endothermic or exothermic?
Answer and Explanation: Crystallization is exothermic (heat evolving). This is because it is a bond-making process, and in chemistry, every bond making process is exothermic….
Why is Naoh dissolving exothermic?
It takes just slightly more energy to separate the ions from one another than is released from the water molecules surrounding the ions. … More energy is released into the solution than is required to pull apart the ions; therefore dissolving sodium hydroxide in water is exothermic.
Is dissolving caused by heat?
The process of dissolving is exothermic when more energy is released when water molecules “bond” to the solute than is used to pull the solute apart. Because more energy is released than is used, the molecules of the solution move faster, making the temperature increase. Project the image Endothermic Dissolving.
Is glucose dissociate in water?
Glucose (sugar) readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity.
Is dissolving sugar endothermic or exothermic?
The process of dissolving sugar in water is endothermic but this is not true for all compounds. Dissolving vinegar (acetic acid) in water, for example, is exothermic.
Is salt dissolving in water exothermic?
Answer and Explanation: Dissolving salt in water is endothermic. This means that when salt is dissolved in water the temperature of the solution is often a little lower than…
Why is glucose very soluble in water?
The hydroxyl groups in glucose molecules can form strong hydrogen bonds with the solvent (water) molecules, so glucose is soluble in water.
What does glucose and water make?
C6H12O6 (s) + H2O (l) → C6H12O6 (aq) If we dissolved any substance in water,it would be formed into it’s aqueous solution. Here we dissolved glucose in water.
What reacts with glucose?
In respiration, through a series of enzyme-catalysed reactions, glucose is oxidized to eventually to form carbon dioxide and water, yielding energy, mostly in the form of ATP. Chemically joined together, glucose and fructose form sucrose.
What happens when glucose is dissolved in water?
When sugar dissolves in water, the weak bonds between the individual sucrose molecules are broken, and these C12H22O11 molecules are released into solution. … The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and the solvent.
What does glucose look like dissolved in water?
A Water-soluble sugar The reason glucose dissolves readily in water is because it has lots of polar hydroxyl groups which can hydrogen-bond with water molecules. Hydrogen bonds are very important intermolecular forces which determine the shape of molecules like DNA, proteins and cellulose.
Does glucose attract water?
– Glucose is a polar molecule. – The positive and negative poles of the glucose molecule will attract water molecules. – The water molecules will then surround each molecule of glucose and weaken the bonds holding it to the rest of the molecules of sugar.
