Step in which glucose is catabolised in animal cell in cytoplasm takes place is called

Options

A. Krebs cycle
B. Glycolysis
C. Oxidative phosphorylation
D. E.T.C.

Answer

**Step-by-Step Solution:**

1. **Identify the Process**: The question asks for the step in which glucose is catabolized in an animal cell in the cytoplasm.

2. **Recognize the Key Term**: The process of glucose breakdown is known as glycolysis.

3. **Location of the Process**: Glycolysis occurs in the cytoplasm of the cell, which is where the enzymes necessary for this process are located.

4. **Understanding Glycolysis**: Glycolysis is an anaerobic process, meaning it does not require oxygen. It involves a series of ten enzymatic reactions that convert glucose into pyruvate.

5. **Products of Glycolysis**: The end product of glycolysis is pyruvate (or pyruvic acid). During this process, energy is captured in the form of ATP and NADH.

6. **ATP Yield**: Glycolysis produces a total of 4 ATP molecules, but since 2 ATP are used in the process, the net gain is 2 ATP. Additionally, the process generates 2 molecules of NADH, which can be used in further energy production pathways.

7. **Conclusion**: Therefore, the step in which glucose is catabolized in an animal cell in the cytoplasm is called glycolysis.

**Final Answer**: Glycolysis
