What are the difference between endotherms and ectotherms?

There's multiple differences between the endotherms and the ectotherms, with the most important being:

- The endotherms maintain a constant body temperature, while the ectotherms's body temperature fluctuates with the environmental temperature.

- The endotherms have developed protection (hairs, feathers) from the outside influences, while the ectotherms do not have such accessories.

- The endotherms are warm-blooded, while the ectotherms are cold-blooded.

- The endotherms are usually bigger if the climate is colder, while the ectotherms are usually bigger if the climate is warmer.

- Endotherms are the mammals and the birds, while ectotherms are the reptiles and most of the invertebrates.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
