2 multiple choice 20 points
when a bear hibernates, they need to use stored energy and insulation while they sleep. which biomolecule would provide this long term energy?
carbohydrates
lipids
proteins

Explanation:

Question 1

To determine the best food for quick energy, we analyze the functions of biomolecules:

• Lipids (oils, nuts) are for long - term energy storage and insulation, not quick energy.
• Proteins (eggs, meat) are for growth, repair, and enzyme/ hormone production, not quick energy.
• Carbohydrates (pasta, bread) are the body's primary source of quick energy as they are broken down into glucose rapidly.

To find the biomolecule for long - term energy and insulation during hibernation:

• Carbohydrates are for short - term energy, not long - term storage or insulation.
• Lipids are ideal for long - term energy storage and also provide insulation (like fat layers in bears).
• Proteins are for structural and functional roles, not long - term energy storage for hibernation.

Answer:

Carbohydrates such as pasta or bread
