When glucose is placed on the tongue, it lowers the temperature by absorbing heat from the tongue. This heat absorption gives the sensation of coldness. Additionally, the process of dissolving the glucose in the saliva can also contribute to the cooling sensation on the tongue.

How are organs kept alive in a translplant?

Organs are kept alive during transplantation through cold storage or machine perfusion techniques that ensure the organ is preserved and functioning properly before being transplanted into the recipient's body. Cold storage involves placing the organ in a cold solution to slow down metabolic processes, while machine perfusion involves using a specialized device to provide oxygen and nutrients to the organ outside the body.


What are the 2 materials produced during photosynthesis?

The equation for photosynthesis is: Carbon dioxide + water + light --> glucose + water + oxygen Therefore, photosynthesis produces glucose (stored in plant as sugar), water (lost through transpiration and kept for the plant), and oxygen (released into air).


5 percent glucose solution is isotonic for red blood cell if red blood cell are kept in 2 percent glucose solution what will happen to the cells. what such a solution called?

2% glucose solution is considered as a hypotonic solution for that the solution will enter the semi-permeable membrane of the red blood cells causing the cells to explode or burst. Why? It's because RBCs have a higher concentration inside it than that of the 2% glucose solution so the solution will enter the cells.


How is the level of sugar in vertebrate blood kept constant?

The blood sugar level is controlled mainly by two hormones.1.Insulin 2.Glucagon.Both hormones are secreted from Pancreas. When blood glucose level (sugar level) increases, Insulin is secreted from beta cells of islets of Langerhans in Pancreas. it increases the cellular uptake of glucose which in turn reduce the glucose level in the blood. When glucose level decreases in the blood, Alpha cells secrete Glucagon. It decrease the uptake of glucose by cells and increase glucose level.Over level of glucose also expelled through urine (Diabetes Mellitus)Mainly insulin & Glucagon are the controllers of blood glucose level.


Why is photosynthesis endothermic reaction?

Photosynthesis is endothermic because it requires energy input from sunlight to drive the conversion of carbon dioxide and water into glucose and oxygen. This energy is used to break the bonds in these molecules and rearrange them into glucose, which stores chemical energy for the plant to use.
