18M.2.SL.TZ2.b.ii
The yellow mealworm (Tenebrio molitor) is native to temperate regions of the world and has been studied as a possible means of producing food in countries with that type of climate. The amino acid content of yellow mealworms and cattle was analysed. The table shows the results for seven amino acids that are required in the human diet.
Predict, with a reason, whether the amino acid composition of yellow mealworms or cattle is more suitable for a human diet.

Markscheme
a. cattle as they are more closely related to humans
b. cattle as they are more likely to have proteins with a similar amino acid composition to humans OWTTE.
c. cattle as they contain a «slightly» higher proportion of «essential» amino acids required in human diet (188 to 176)
OWTTE
