This section is Section 2 of 3.

Speed as well as accuracy is important in this section. Work quickly, or you might not finish the paper. There are no penalties for incorrect responses, only marks for correct answers, so you should attempt all 27 questions. Each question is worth one mark.

You must complete the answers within the time limit. Calculators are NOT permitted.

Good Luck!

1. Which row of the table below correctly identifies the types of nutrient 1, 2 and 3?
  • 0
    0

    Explanation

    The correct answer is B.

    Looking at the first column titled ‘mouth’, only digested food of nutrient 1 is present, whilst nutrients 2 and 3 remain fully digested. Only starch is digested in the mouth (by salivary amylases), therefore nutrient 1 must be starch. So the answer must be B or E. Looking at the second column titled ‘stomach’, nutrient 2 is partially digested whilst nutrient 3 remains fully undigested. Only proteins are digested in the stomach (by proteases such as pepsin), therefore nutrient 2 must be protein. Therefore B is the correct answer.
