Endothermic reactions are those in which energy is absorbed from the surroundings. This can occur in the form of heat, light, or electricity, as seen in processes like the decomposition of silver chloride in sunlight.

In black and white photography, light-sensitive silver halide crystals, such as silver chloride, undergo decomposition when exposed to light, forming metallic silver particles that create the photographic image.

White silver chloride turns grey in sunlight due to the decomposition of silver chloride into silver and chlorine by light energy.

Glucose is metabolized in the cells through a series of biochemical reactions, primarily aerobic cellular respiration. This process involves the oxidation of glucose in the presence of oxygen, resulting in the release of energy that is used to fuel various ...

Carbohydrates are broken down into glucose during digestion. Glucose then combines with oxygen in the cells through cellular respiration to produce energy in the form of ATP (adenosine triphosphate).
