Final answer:
To support claims about a carbohydrate digestion product, one can refer to the role of digestive enzymes such as amylase in the breakdown of complex carbohydrates. The inclusion of beneficial bacteria could also be relevant regarding lactose digestion but is less directly related to the process of carbohydrate digestion in the stomach and small intestine.
Step-by-step explanation:
The evidence that could be used to support the claims about a product designed to aid in the digestion of carbohydrates are based on the understanding of how digestion works:
- Option (a) could be supported by the knowledge that digestive enzymes such as amylase and other carbohydrase enzymes assist in breaking down complex carbohydrates into simpler sugars (monosaccharides and disaccharides), which is then followed by absorption in the small intestine. Amylase, which begins its work in the mouth, continues in the small intestine with the aid of the pancreatic amylase and brush border enzymes like maltase and sucrase.
- Option (b) is less accurate as beneficial bacteria typically aid in the process at a later stage in the large intestine, primarily with fibers that are not digested by human enzymes. However, it is true that certain gut bacteria can aid in the digestion of lactose.
