What type of macromolecule is primarily responsible for long-term energy storage?

Back

Lipids are the macromolecules responsible for long-term energy storage.

Front

How do enzymes function and what factors affect their activity?

Back

Enzymes are biological catalysts that speed up chemical reactions. Their activity can be affected by temperature, pH, and substrate concentration.

Front

What is the role of lipids in aquatic birds' feathers?

Back

Lipids provide a waxy coating that repels water, helping to keep the feathers dry.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

How do carbohydrates differ from lipids in terms of structure and function?

Back

Carbohydrates are composed of sugar molecules and primarily provide energy, while lipids are made of fatty acids and glycerol and are used for energy storage and insulation.

Front

What is the significance of high temperature for enzyme activity?

Back

High temperatures can increase enzyme activity up to a certain point, but excessive heat can denature enzymes, leading to loss of function.

Front

What are the main types of macromolecules found in living organisms?

Back

The main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

What is the difference between simple and complex carbohydrates?

Back

Simple carbohydrates consist of one or two sugar units and provide quick energy, while complex carbohydrates are made of many sugar units and provide sustained energy.
