Answer:
In chemical digestion, enzymes break down food into the small molecules the body can use. It is important to break down macromolecules into smaller fragments that are of suitable size for absorption across cell membranes.
Amino acids are the monomers that makes up protein
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.
BONDING. 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. ... Different atoms use these electrons to form one of three different types of bond: ionic bonds, covalent bonds, or metallic bonds.
Proteins. ...
Lipids. ...
Carbohydrates. ...
Nucleic Acids.
Respiration, which consists of three phases, occurs in the mitochondria, the cell's “powerhouses.” This metabolic pathway traps the maximum amount of stored chemical energy within a molecule of glucose, generating a total of 30 molecules of ATP in conjunction with glycolysis.
