Macromolecules

LEQ: How does food provide the energy and molecules required for building materials, growth, and survival of all organisms?

Key Concepts:

• Matter is transferred among organisms in an ecosystem when organisms eat, or are eaten by others for food.
• Matter is transferred from organisms to the physical environment when molecules from food react with oxygen to produce carbon dioxide and water in a process called cellular respiration.
• Through the process of cellular respiration, cells convert energy (glucose) to a usable form of energy (ATP).
• The energy stored in ATP provides the means by which cells are able to carry out their functions such as growth, development, and repair of organisms, locomotion and transportation of molecules across cell membranes.
• Plants use the energy from light to make sugars (food) from carbon dioxide and water. This process transforms light energy from the sun into stored chemical energy.
