Enzymes: function, structure and specificity

Explaining effects of substrate concentration and temperature on enzyme rate

The effect of pH on the rate of an enzyme reaction: plan

The effect of pH on the rate of an enzyme reaction: practical

The effect of pH on the rate of an enzyme reaction: data analysis

Pupils will learn how substances essential for chemical reactions, and the products of the reactions, are transported into, around and out of the human body.

Pupils learned about differences in the cell structures of eukaryotic and prokaryotic organisms.

This unit explores the roles of sugars, amino acids, and fatty acids in the synthesis and breakdown of biological molecules. It covers enzyme action, transport in organisms, hypothesis development, and data interpretation. Emphasis is on planning experiments and presenting explanations.
