Breakdown of glucose is called …………….. while formation of glucose from non - carbohydrate sources is called ………………

Explanation

To answer the question, we need to identify the two processes mentioned: the breakdown of glucose and the formation of glucose from non-carbohydrate sources.

1. **Breakdown of Glucose**:
- The process of breaking down glucose is known as **Glycolysis**. In this metabolic pathway, glucose is converted into pyruvate, which is a crucial step in cellular respiration. The term "glycolysis" comes from the Greek words "glyco," meaning sugar, and "lysis," meaning splitting. Therefore, glycolysis refers to the splitting of sugar.

2. **Formation of Glucose from Non-Carbohydrate Sources**:
- The process of forming glucose from non-carbohydrate sources is called **Gluconeogenesis**. This metabolic process allows organisms to produce glucose from non-carbohydrate precursors such as lactate, glycerol, and glucogenic amino acids. It is essentially the reverse of glycolysis and is vital for maintaining blood glucose levels during fasting or intense exercise.
