Muscle Cells Flashcards
1
Q

A
Muscle cells are specialised to contract quickly to move bones or to squeeze, therefore causing movement.
2
Q
What muscle contracts quickly to move bones?
A
The striated muscle.
3
Q
What muscle squeezes to cause movement and where are they found?
A
The smooth muscle- which are found in blood vessels so blood pressure can be varied.
4
Q
What do myosin and actin do?
A
Myosin and actin slide over each other, causing the muscle to contract.
5
Q
What do muscle cells have lots of and why?
A
Muscle cells have lots of mitochondria to provide energy from respiration for contraction.
6
Q
What does muscle cells store and what is it used in?
A
Muscle cells store glycogen that is used in respiration by the mitochondria.
