Question

1. a student conducting an experiment uses benedicts solution (turns from blue to green in the presence of glucose) to test two different carbohydrate solutions. both the maltose solution and glucose solution give a positive result. why would the maltose solution give a positive result? 10. in todays world, it is very easy to promote misinformation. one of the many ways people are misinformed is with nutrition. diet companies promote their products and diets to make money off of individuals looking to improve their health. often these products and diets can cause more harm than good. suggest a reason for why it would not necessarily be healthy for someone to eliminate “carbs” from their diet?

Explanation:

For question 9, maltose is a disaccharide that can be hydrolyzed into two glucose molecules. Benedict's solution reacts with reducing sugars like glucose, and maltose is a reducing sugar due to its ability to be broken down into glucose, thus giving a positive result. For question 10, carbohydrates are the body's main source of energy. Eliminating them can lead to fatigue, decreased brain function as the brain relies on glucose for energy, and may disrupt the normal functioning of the digestive system which is adapted to process carbohydrates.

Answer:

1. Maltose is a reducing sugar and can be hydrolyzed to glucose.
2. Carbohydrates are the body's main energy - source and their elimination can cause multiple negative impacts on the body.
