2.1: Molecules to Metabolism

All of the chemical reactions that take place in a cell or organism is called

• metabolism

• catabolism

• redox reactions

• phosphorylation

When large molecules are being formed by chemical reactions it is called

• anabolism

• catabolism

• photosynthesis

• respiration

When molecules are being broken down in a chemical reaction it is called

• anabolism
• catabolism
• photosynthesis
• uptake

Carbohydrates contain the following elements:

Polymers are broken down into monomers by the process of:

• hydrolysis

• dehydration synthesis

• condensation synthesis

• hydrosynthesis

Monomers form polymers by:

• hydrolysis

• condensation lysis

• the removal of water

• the addition of water
