Differentiate between the following pairs on the basis of what is given in the brackets:
Glycolysis and Kreb.s cycle (Amount of energy released)

Explanation

### Step-by-Step Solution:

1. **Definition of Glycolysis and Krebs Cycle**:
- Glycolysis is the metabolic pathway that converts glucose into pyruvate, releasing a small amount of energy in the form of ATP and NADH. It occurs in the cytoplasm and can take place in both aerobic and anaerobic conditions.
- The Krebs cycle (also known as the citric acid cycle or TCA cycle) is a series of chemical reactions used by aerobic organisms to generate energy. It occurs in the mitochondria and is part of aerobic respiration.

2. **Energy Release in Glycolysis**:
- During glycolysis, the breakdown of one molecule of glucose results in the production of 2 molecules of ATP and 2 molecules of NADH.
