Question

1. what are carbohydrates primarily used for in the body? building muscle providing energy improving digestion enhancing memory 2. which type of carbohydrates can lead to a crash after an energy boost? complex carbohydrates fiber - rich carbohydrates simple carbohydrates protein - rich carbohydrates 3. what happens to glucose that is not immediately used by the body? it is excreted. it is converted into protein. it is stored in the liver as glycogen. it turns into fat immediately.

Explanation:

1. Carbohydrates are broken down into glucose, which is the body's main energy source. Proteins build muscle, fiber (a type of carbohydrate) aids digestion, and there's no primary role of carbs in enhancing memory.
2. Simple carbohydrates (like sugars) are quickly digested, causing a rapid energy spike followed by a crash as blood sugar drops. Complex carbs are digested slower, fiber - rich carbs (like in whole grains) have other benefits, and "protein - rich carbohydrates" is not a standard category.
3. Glucose not immediately used is stored in the liver (and muscles) as glycogen. It's not excreted (unless in certain medical conditions like diabetes), not converted to protein (amino acids build protein), and not immediately turned to fat (stored as glycogen first, then can be converted to fat if glycogen stores are full).

Answer:

1. Providing energy
2. Simple carbohydrates
3. It is stored in the liver as glycogen
