How the lactic acid produced in milk by Lactobacillus bacteria changes the milk into curd? Justify your answer.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Components**: Milk contains a sugar called lactose, which is a disaccharide made up of glucose and galactose. It also contains proteins, fats, vitamins, and minerals.
