Answer:
1.What happens to macromolecules from food during digestion?
They are broken down into smaller molecules and are made into ATP (cellular respiration), or into storage fat for the body's reserve energy. They are broken down in a process called hydrolysis.
2.What atoms make up sugar molecules, amino acids, and fatty acids?
Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom bonded to an amino group (–NH2), a carboxyl group (–COOH), and a hydrogen atom.
3.What do you notice about the atoms that make up these molecules?
If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
4.How are these atoms used to make new molecules? What types of molecules are made?
When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. It is only the electrons in the outermost shell that ever get involved in bonding.
5.Where does the energy come from to produce these new molecules?
The energy comes from the mitochondria, the powerhouse of the cell.
