Ever wondered how skeletal muscles function? 
This is one of the mammalian physiology concepts you will study in A-level Biology.
Could you explain the role of calcium ions in muscle contraction?
What about the function of ATP in muscle contraction?
What happens to tropomyosin during a contraction?Can you explain the sliding filament theory?Can you identify the A band, Z line, I band and H zone in a myofibril?Determined to reach the highest grades?Determined to fully understand all biological concepts?Determined to achieve your predicted grades?Determined to follow your university degree?Contact Nicky Tweedle’s Biology Tuition for further details:
