Nucleotides consist of three parts:• a 5-carbon sugar

• a phosphate group

• a nitrogenous base

Page 4: Copyright Pearson Prentice Hall Nucleic Acids – C, H, O, N, P are made from nucleotides

Made of long chains of amino acids.

PROTEINS – C, H, O, N

The R-group differs in each amino acid.

Some functions of proteins:

–Control the rate of reactions (Enzymes)

–Used to form bones and muscles

–Transport substances into or out of cells

–Help to fight disease (antibodies)

Enzymes – act as catalyststhey speed up reactions,

but are not used up in the reaction

Catalysts reduce the activation energy needed to start the reaction,

allowing the reaction to go faster

Enzymes can be affected by: Changes in pH or temperature

Heat or Acids break the H bonds, changing its shape.

If its the wrong shape, it can’t function.
