To begin with, we should first look at how the heart beats.
Beating of the heart is due to myogenic muscle contraction, This means the myocyte (muscle cell) itself is the origin of the contraction an...

ATP binds the myosin head in its resting state. ATP is hydrolysed to ADP + Pi, releasing energy. This changes the conformation of the myosin head, cocking it. The myosin head reattaches to the actin molec...

Diffusion refers to the process where particles (molecules and ions) move from an area of high concentration to an area of lower concentration. I would draw a diagram of ...

Atp/pc system- ATP is hydrolysed into ADP + Pi, the free phosphate is used in exercises of 2-10s such as a powerlift.Anaerobic energy system- Glucose is the fuel for energy of glycolysis- used in exercise...
