Muscle Cells
Biology: AQA GCSE Higher, topic 1.1.18
Muscle Cell
Muscle cells are specialised (perform a specific function). They can produce force and motion.
Mitochondria
- A muscle cell contains lots of mitochondria to generate lots of energy for motion.
Protein fibres
- Protein fibres within the cell can contract, allowing the muscle to move.
Test yourself on Muscle Cells
How do the adaptations of a muscle cell work together?
Why do all the cells in a sample of heart muscle contract together?
How do the cells in a sample of heart muscle behave when the muscle contracts?
What does the coordinated contraction of heart muscle cells show about muscle cells in general?
Why does a muscle cell need many mitochondria before its protein fibres can contract?
