The first stage of glucose break down in animal cells is Glycolysis.
Glycolysis:
- Glycolysis is the process by which glucose is broken down into pyruvate.
- It occurs in the cytoplasm of the cell.
- It is an anaerobic process, meaning it does not require oxygen.
- The process produces a small amount of ATP (energy) and NADH (a molecule that carries energy).
Steps of Glycolysis:
1. Glucose is phosphorylated by ATP to form glucose-6-phosphate.
2. Glucose-6-phosphate is converted to fructose-6-phosphate.
3. Fructose-6-phosphate is phosphorylated by ATP to form fructose-1,6-bisphosphate.
4. Fructose-1,6-bisphosphate is split into two molecules of glyceraldehyde-3-phosphate (G3P).
5. Each G3P molecule is oxidized and phosphorylated to form two molecules of pyruvate.
6. The process produces a small amount of ATP and NADH.
Overall, glycolysis is an important process in the breakdown of glucose in animal cells, as it produces a small amount of energy and precursor molecules for further energy production pathways.
