Scenario: You are studying an animal that lives in a cold environment, such as the Arctic. The animal has a thick layer of fat beneath its skin. This helps the animal stay warm and survive in freezing temperatures.
Question: How do lipids, as macromolecules, help this animal survive in cold environments?

By providing energy through photosynthesis

By acting as enzymes to speed up reactions in the body

By storing energy and providing insulation to keep the body warm

By helping the animal breathe underwater

Cellulose, starch, and glycogen are all types of carbohydrates but serve different purposes. Cellulose is found in plant cell walls and gives plants their structure; humans can’t digest it, so it helps with digestion as fiber. Starch is how plants store energy, and we get energy from it when we eat foods like potatoes and bread because our bodies break it down into glucose. Glycogen is how animals, including humans, store energy in the liver and muscles; it’s our quick energy reserve that we use when we need an energy boost.

Plants store excess carbohydrates as .
