Practice objective / multiple choice question 3 from the 2021 Neco Model Questions Vol1 Biology examination.
The diagram shows the small intestine of an adult human, whose total length is 600 cm. The intestine is divided into three segments: duodenum (25 % of the total length), jejunum (45 % of the total length) and ileum (30 % of the total length). Glucose is absorbed in the jejunum at a rate of 0.5 g per centimetre and in the ileum at a rate of 0.2 g per centimetre. No significant absorption occurs in the duodenum. If a person ingests 180 g of glucose, how many grams are absorbed in the jejunum, assuming absorption proceeds until the ingested amount is exhausted?
