Matter
What is all matter made of?
Atoms
Give an example of a type of energy.
Motion, heat, light, chemical.
What carbon transformation process "burns" organic molecules?
Combustion
What is the carbon transformation process that converts food into usable energy?
Cellular respiration
What carbon transformation process in plants converts inorganic molecules into glucose?
Photosynthesis
What do atoms form when bonded together?
Molecules
Where is energy found in a molecule?
The bonds
What is produced when ethanol burns?
Where does cellular respiration take place in the cell?
Mitochondria
Where does photosynthesis take place in the cells?
Chloroplasts
Is carbon made of atoms or molecules?
Atoms
Why does energy have to be converted into other forms?
It can't be created or destroyed.
What is MOST of the mass converted into when ethanol burns?
Carbon dioxide
How do animals grow?
SOMs into LOMs or biosynthesis
What energy transformation happens in photosynthesis?
Sunlight into chemical energy
Why does air have mass?
Air contains atoms and molecules, like argon, carbon dioxide, nitrogen, oxygen, etc. These all have mass.
What category of molecule has chemical energy?
Organic molecules
Where does energy for the flame in ethanol burning come from?
The chemical bonds in ethanol
What energy transformation happens cellular respiration?
Chemical into motion/heat/cell functions
Explain where gas exchange occurs in plants, what molecules are exchanged and when.
Stomata. CO2 for O2 during daytime. O2 for CO2 during nighttime.
How can an organism gain mass?
By gaining atoms
Why doesn't carbon dioxide have energy?
It doesn't contain C-C or C-H bonds.
How does a car have the energy to move you wherever you decide to go?
There is energy in the bonds of the fuel. They're converted into motion energy through combustion.
How is it possible for an organism to gain 1lb and defecate 0.5lb when it ate 5lb of food?
Cellular respiration releases carbon dioxide gases, which accounts for MOST of the mass lost.
What type of energy is in a living plant?
Chemical, heat, motion (or energy used for cell functions)
