Here's a breakdown:
* Starch: A complex carbohydrate made of glucose molecules linked together. Plants use starch to store energy.
* Glycogen: Also a complex carbohydrate made of glucose molecules, but it's structured differently than starch. Animals store glycogen primarily in the liver and muscles.
Key differences:
* Structure: Starch and glycogen have different branching patterns, affecting how easily glucose can be released.
* Location: Plants store starch in various parts, while animals store glycogen in specific organs.
* Function: Both are used for energy storage, but glycogen is more readily accessible for animals.
Think of it like this: starch is the plant's pantry, while glycogen is the animal's emergency snack stash.
