You were running late for class, so in an effort to be efficient, you decided to combine your milk and orange juice in one glass so that you could drink both together. Not only did it taste gross, but the milk actually curdled. What caused the milk to curdle? (hint: orange juice is an acidic product) The orange juice changed the primary structure of the milk proteins. The milk proteins acted as an emulsifier between the orange juice and the lipids in the milk. The milk proteins were denatured due to the acidity of the orange juice. Gelation occurred between the milk protein and the pulp in the orange juice.

The milk proteins were denatured due to the acidity of the orange juice.

Explanation:

Any acidic solution, such as the orange juice in this example, would make milk curdle. The milk curdled because of the acidity of the orange juice made the milk proteins denatured.

That's because orange juice is an acidic solution while milk acts as a buffer, meaning it shields the acidity of the orange juice, making the milk curdle.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
