Muscle tissue is tissue that composes all types of muscles, skeletal, cardiac and smooth muscles. There are four main common properties of all muscles:
- Contractility-ability to contract. In the case of skeletal muscles it is voluntary, while in cardiac and smooth muscles it is unconscious.
- Excitability-ability to change membrane potential usually by the influence of nervous impulse.
- Extensibility-the capacity to lengthen
- Elasticity-ability to change its length and then return to previous.
Transport proteins require energy because they are pumping materials. Without energy, they won't function and we will have huge problems in our body.
I hope this helps! :D
