Biochemistry and Macromolecules

Which of the following is not a carbohydrate?

• Fructose

• glycerol

• cellulose

• disaccharide

The basic units of Lipids are called:

• simple sugars

• nucleotides

• amino acids

• fatty acids

When two amino acids join together they form:

• Glyosidic bond

• Peptide bond

• Saccharide bond

• Protein bond

Which nucleotide stores the greatest amount of energy?

• AMP

• ADP

• ATP

• energy is the same in all 3.

What is activation energy?

• energy needed to start a chemical reaction.

• energy given off during a chemical reaction.

• energy absorbed during a chemical reaction.

• a type of kinetic energy.

What type of reaction is described by the equation maltose + water gives us glucose?

• synthesis

• catalyst

• hydrolysis

• dehydration synthesis

Proteins are used by the human body:

• to help with your main food source.

• as a source of simple sugars.

• by being converted to fat and stored.

• a source of essential amino acids.

The total of all the chemical reactions that occur within a cell is called:

• potential energy

• activation energy

• metabolism

• homeostasis

A carbohydrate is best described as:

• a carbon atom attached to a water molecule.

• a sugar molecule attached to water

• fructose and sucrose

• bad for you

When a cell is placed in hypertonic solution:

• it will burst

• it will shrink in size

• nothing happens

• it becomes hypotonic
