What is glycolysis and why is it important?
Our cells obtain their energy from glucose. However, they cannot use it directly. First, they need to transform the energy from glucose to the form of energy that they can use. Cells use energy in the form of ATP. Thus, a cell transforms the energy in glucose to ATP, the form of energy that they can utilize. The process in which this occurs is cellular respiration. Glycolysis is the initial step of cellular respiration. The end products of glycolysis are used further during cellular respiration. Therefore, glycolysis is very important.
What is made and what is used during glycolysis?
Glycolysis uses 2 ATP molecules, but it makes 4 ATP molecules. Thus, our net gain will be: 4 ATP - 2 ATP = 2 ATP. During glycolysis, the cell also produces two NADH molecules. Water is also released.
Where does glycolysis occur?
Glycolysis occurs in the cytoplasm of the cell:
