Water is a major component of cells
Water makes up the majority of every living cell. Most animal cells are roughly 70–80% water by mass.
Real World
When scientists at the Wellcome Sanger Institute analyse human liver cells, roughly 70% of each cell's mass is water — remove it and enzymatic activity collapses entirely.
Exam Focus
If asked to 'explain' the importance of water as a cell component, always link its abundance to the aqueous environment enzymes require.
Evaluation Scaffold
A four-step framework for high-quality evaluation. Use this for 'assess', 'evaluate', and 'to what extent' questions.
