Energy and the Chemistry of Life (18:27)
Matter is anything that occupies space and has mass. Energy is the capacity to do work. Atoms, which contain neutrons, protons, and electrons, bond to form molecules. All living things are composed of the same elements: hydrogen, oxygen, carbon, and nitrogen. Sugar is a carbohydrate that provides energy, lipids store energy, proteins function as enzymes, and nucleic acids process and store information.
Chemistry of Food (9:56)
Learn how chemistry and thermodynamics help food scientists determine the calorie content of your favorite foods.
The World of Plants: Photosynthesis (13:27)
Photosynthesis looks at the critical role this process plays in providing food and oxygen. An explanation is given of the key steps involved, and the importance of the process to almost all other living organisms is stressed.
Biology: The Science of Life: The Flow of Matter and Energy in the Living World: Photosynthesis and Cellular Respiration (15:07)
Review basic concepts such as matter, energy, elements, atoms, molecules, chemical bonds, chemical compounds, chemical reactions, and chemical equations. Then by focusing on photosynthesis, cellular respiration, and food chains, discover how matter and energy flow through the living world.
