Cells need ATP for active transport, muscle contraction, protein synthesis and nerve impulses.

Step-by-step lessons on Eduqas A Level Biology Respiration releases chemical energy in biological processes. Each one builds up to exam-style questions. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
