kicyunya [14]

There are different function performed by carbohydrates in the body like-

Storage: When there is excess glucose present in the body they are stored as glycogen in muscles and liver.

Providing energy: Carbohydrates are the primary source of energy for the cells present in our body.

Carbohydrate helps to spare proteins and lipids and helps in providing polysaccharides for membrane carbohydrates.

The body maintains blood glucose levels through hormones. For example, when the blood glucose level gets high insulin is released in the blood by the pancreas which reduces the blood glucose level by accumulating glucose as glycogen in the liver and muscle.

Glucagon works opposite to insulin and increases the blood glucose level.

What kind of channels are located in the input region?
tamaranim1 [39]

Answer:

The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).

Explanation:

Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.

The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.

The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.

Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.
