The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Pulses**: Pulses are a group of legumes that are considered a rich source of proteins, which are made up of amino acids. They are also known for their ability to fix nitrogen in the soil. 2. **Amino Acids in Pulses**: There are 20 different amino acids that are important for human nutrition. While pulses are rich in many amino acids, they do not contain all of them in adequate amounts. 3. **Identifying Deficiencies**: Among the amino acids, pulses are known to be particularly low in certain essential amino acids. The question specifically asks which amino acids are usually lacking in pulses. 4. **Key Amino Acids**: The amino acids that are often deficient in pulses include methionine and cysteine. Methionine is an essential amino acid that is crucial for various bodily functions, including protein synthesis and metabolism. 5. **Conclusion**: Based on the information, pulses usually lack the amino acids methionine and cysteine. Therefore, the correct answer to the question is that pulses usually lack amino acids cysteine and methionine. ### Final Answer: Pulses usually lack amino acids: **Cysteine and Methionine**. ---
