Water - Biological molecules. AQA A-level biology 7401

2 lessons which cover all the learning objectives for the water lesson from the biological molecules unit of the course (AQA A-level biology 7401 year 1).

Learning objectives covered are:
• Water is a major component of cells. It has several properties that are important in biology.
• Water is a metabolite in many metabolic reactions, including condensation and hydrolysis reactions
• Water is an important solvent in which metabolic reactions occur
• Water has a relatively high heat capacity, buffering changes in temperature
• Water has a relatively large latent heat of vaporisation, providing a cooling effect with little loss of water through evaporation
• Water has strong cohesion between water molecules; this supports columns of water in the tube-like transport cells of plants and produces surface tension where water meets air.

Includes activities (e.g. questions and answers, quick check tasks, structure strip activity and homework question).
