The process of making glucose without light energy from the sun is called gluconeogenesis.

Here's a breakdown:

* Gluconeogenesis is a metabolic pathway that creates glucose from non-carbohydrate sources, primarily pyruvate, lactate, glycerol, and glucogenic amino acids.

* It occurs primarily in the liver and kidneys.

* It is essential for maintaining blood glucose levels during fasting or prolonged exercise when carbohydrate stores are depleted.

* It requires energy in the form of ATP and GTP.

Key points to remember:

* Photosynthesis is the process of using light energy to create glucose from carbon dioxide and water. This is how plants obtain their energy.

* Gluconeogenesis is a different process that occurs in animals and some bacteria. It uses energy from other sources to create glucose.
