Digestion is the process of breaking down large food  molecules into smaller molecules that can be absorbed into the blood.

An enzyme is a biological molecule that is a catalyst that speeds up the rate of a reaction.

A carbohydrate is a molecule made of carbon, hydrogen and oxygen, and provides energy.

A protein is a molecule made of amino acids, and is used for growth and repair.

A fat is a molecule that is stored and used for energy.

Pupils will learn how cells use sugar from digested food as a source of energy.

Pupils learned that particles of substances move within, into and out of cells by diffusion.

This unit examines the human digestive system, including the roles of tissues, organs, enzymes, and beneficial bacteria. It also focuses on evaluating risks, interpreting data, identifying patterns, and suggesting improvements to enhance the reliability of investigations.
