Muscles can only pull and can’t push. This means two muscles have to work together at a joint. This is called an antagonistic pair.

6. Task
Who can remember the function of mitochondria? How is mitochondria useful for muscles?
Muscles work hard so their cells need a lot of energy. Respiration releases energy and occurs in mitochondria.
So, will muscle cells contain more or less mitochondria than another type of cell? More

7. TASK
Order the sentences to describe the movement of an antagonistic pair
The bicep begins to contract and the tricep relaxes lifting the ball
The arm is fully bent towards the body
The tricep is contracted while the bicep is relaxed and the arm is extended
The bicep is fully contracted and the tricep is fully relaxed
Muscles can only pull and can’t push. This means two muscles have to work together at a joint. This is called an antagonistic pair

8. TASK Write these steps in your books
The tricep is contracted while the bicep is relaxed and the arm is extended
The bicep begins to contract and the tricep relaxes lifting the ball
The arm is fully bent towards the body
The bicep is fully contracted and the tricep is fully relaxed

9. Thinking Skills Leg bone, leg muscle, fat Odd One Out
