B. Fats are being emulsified
C. Protein is being digested
D. Starch is being digested

Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Jawaban:

The answer is: None of the above options (A, B, C, or D) are correct.

Penjelasan:

As a bolus of food passes along the oesophagus, the primary process occurring is the propulsion of the food from the mouth to the stomach via a wave-like muscle contraction called peristalsis. This movement is not associated with digestion of any nutrients in the food.

Digestion of the bolus of food, which includes the breakdown of fats, proteins, and starch, primarily occurs in the stomach and small intestine. Therefore, fats are not being digested or emulsified, protein is not being digested, and starch is not being digested while the bolus is in the oesophagus.
