Question

In this module, you learned that special channels called aquaporins allow water to move between cells. These channel proteins are selective- they freely let water molecules through the membrane but NOT ions or other molecules- but (like leak channels) are not gated. Based on those facts, state which of the following would be the most likely to determines the direction (and how quickly) water can move across a membrane using aquaporins, and (in a few sentences) explain your answer. how much ATP is present inside the cell what the resting membrane potential is what the concentration of different solutes are on the inside of the cell relative to the outside of the cell As you learned, a neuron controlling a muscle converts the electrical signal into a chemical signal by releasing the neurotransmitter acetylcholine in to the synapse between the two cells. In 4-6 sentences, summarize how the chemical signal is converted back in to an electrical signal into an electrical signal in the postsynaptic muscle cell.

Explanation / Answer

ANSWER 4:

As water movement through aquaporin is passive process,most likely factor that favour transport of water through aquaporin is concentartion of different solutes across membrane that helps to generate osmotic gradient and water transport depends on osmotic pressure across the membrane.

Aquaporins provide passive pathway for transport that's why presene or absence of ATP doesn't affect the rate of transport through aquaporins.
