Metabolism & Review

The molecules in a cell that are large and complex are called

• organelles
• macromolecules
• organs
• cytoplasm

The element from the periodic table that is referred to as the "atom of life" is

• oxygen
• carbon
• nitrogen
• hydrogen

Carbon atoms, inside cells, can form long chains or 

• rings
• branches
• squares
• cytoplasm

A very large molecule that is made up of hydrogen, carbon and oxygen is very important for fuel for our bodies.  Another term for this molecule is a "sugar".  What is the formal name for this molecule?

• carbon
• metabolism
• carbohydrate
• macromolecule

A single sugar molecule is called a

• macromolecule
• disaccharide
• polysaccharide
• monosaccharide

A long strand of sugars linked together is called a

• chain
• ring
• macromolecule
• saccharide

A double sugar is called a

• polysaccharide
• monosaccharide
• disaccharide
• macromolecule

Sugars that form a closed unit are called

• chains
• rings
• saccharides
• macromelecules

A sugar is a sugar is a sugar.  What is another name for a sugar?

• carbohydrate
• ring
• metabolism
• chain

Since a sugar is a sugar is a sugar, we scientists must name things in different way so we are very complicated.  Soooooo, another name for a sugar is a

• sacchharide (mono-, di-, or poly-)
• macromolecule
• metabolism
• carbon
