5 Questions
What is the main purpose of metabolism in an organism?
To convert food energy into energy needed for various functions
According to the First Law of Thermodynamics, what happens to energy?
Energy is converted from one form to another
What is the main purpose of photosynthesis?
To convert carbon dioxide, water, and minerals into organic compounds and oxygen
What is the role of starch in the energy cycle?
Starch is a rich energy source stored in plants like grass, which is broken down into glucose by animals for energy production and growth
How do humans utilize the energy from carbohydrates, fats, and proteins?
Humans further digest carbohydrates, fats, and proteins into individual atoms, which are then utilized to form new tissues and energy sources to support human life and activity
Study Notes
- Metabolism encompasses all chemical processes in an organism, allowing the body to convert food energy into energy needed for various functions like thinking, tissue repair, and muscle movement.
- The First Law of Thermodynamics states that energy is not created or destroyed, but rather converted from one form to another.
- Photosynthesis is a crucial process driven by sunlight energy, where plants convert carbon dioxide, water, and minerals into organic compounds and oxygen, sustaining life on Earth.
- Starch, made up of glucose molecules, is a rich energy source stored in plants like grass, which is broken down into glucose by animals like cows for energy production and growth.
- Humans further digest carbohydrates, fats, and proteins into individual atoms, which are then utilized to form new tissues and energy sources to support human life and activity.
