Which type of carbohydrate is formed by linking together hundreds of sugar units?Multiple choice question.polysaccharidedisaccharidemonosaccharide

Step 1: Break Down the Problem

The question asks for the type of carbohydrate formed by linking together hundreds of sugar units, which necessitates an understanding of the classifications of carbohydrates.

Step 2: Relevant Concepts

1. Monosaccharides: These are the simplest form of carbohydrates, consisting of single sugar units (e.g., glucose, fructose).
2. Disaccharides: These carbohydrates are formed by linking two monosaccharides (e.g., sucrose is made of glucose and fructose).
3. Polysaccharides: These carbohydrates consist of long chains of monosaccharide units linked together, often hundreds or thousands, such as starch and cellulose.

Step 3: Analysis and Detail

Given the definitions:

• Monosaccharides are single units, so they do not fit the description of being "hundreds."
• Disaccharides consist of just two units, thus also do not meet the criteria.
• Polysaccharides, on the other hand, are indeed formed by the linkage of many monosaccharide units.

Step 4: Verify and Summarize

From the breakdown, it's clear that polysaccharides are the type of carbohydrate formed by linking together hundreds of sugar units.

Final Answer

Polysaccharide is the correct answer.
