I believe it would be the bending of the arm, utilizing your muscular ad skeletal system. As the joint in your elbow is cartilage part of the skeletal system, and the voluntary bending comes from the contraction of muscles in the arm.
Answer:
(b) Are Voltage-gated channels
Explanation:
Transmitter gates ion channels are also called ionotropic neurotransmitter receptors as one or more parts of the ion channel serve as a receptor for specific neurotransmitters.
Binding of the specific neurotransmitter to the receptor stimulates the opening of the ion channels and allows the transmembrane transport of specific ion.
The voltage-gated ion channels are the ones that open and close in response to changes in the voltage across the plasma membrane.
For example, voltage-gated Na+ channels are opened in response to depolarization of the membrane only.

The leaves of a plant contain the most chloroplasts. Plant leaves are the largest area of the plant while chloroplasts are used during photosynthesis to create a reliable source of food for the plant to use. Hence, many chloroplasts are found on the leaves of plants in order to gather light energy from the sun to create the greatest possible amount of food for the plant to consume.
