Question

carbohydrates can also be used as short term storage of energy in plants as ______ and in animals as ______, for later use. glucagon and insulin cellulose and chitin dna and rna starch and glycogen

Explanation:

To solve this, we analyze each option:

• Glucagon and insulin are hormones (not energy - storage carbohydrates), so this option is incorrect.
• Cellulose (plant structural) and chitin (fungal/exoskeleton structural) are not for short - term energy storage, so this option is wrong.
• DNA and RNA are nucleic acids (not carbohydrates for energy storage), so this option is incorrect.
• Starch is the short - term energy - storage carbohydrate in plants, and glycogen is the short - term energy - storage carbohydrate in animals. This matches the description in the question.

Answer:

starch and glycogen (the option with "starch and glycogen")
