Answer:

A) Channel Protein

Explanation:

Channel proteins span the membrane and make hydrophilic tunnels across it, allowing their target molecules to pass through by diffusion.

Channels are very selective and will accept only one type of molecule to transport

A channel protein, a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly.

In what ways are autorhythmic fibers similar to and different from contractile fibers?
Leto [7]
I think Autorhythmic fibers are fibers that are self excitable or on their own for example some cardiac muscle. They  repeatedly generate action potentials that trigger heart contractions.They continue to stimulate a heart to beat even when it is removed from the body. In comparison to contractile fibers, autorhythmic fibers are self excitable and do not require nervous system stimulation to trigger contractions. Contractile fibers have stable resting membrane potentials of -90mV, when a contractile fibers reaches threshold by action potential, the voltage gated fast sodium ions channels will open.
