Answer:
( a ) Voltage gated channels - channel can open and close based on membrane potential. At rest, the channel is closed and it opens at threshold.
Explanation:
Voltage Gated Channels -
It is a channel with a cluster of proteins present in the membrane .
The function of voltage - gated channel is to open for the some values of membrane potential and close for others . In maximum cases , the relation between channel state and membrane potential is probabilistic and requires a time lag . The ion channel can even flip the conformations at an unpredictable times , the membrane potential even determines the rate of transition and the probability per unit time of each and every transition .
 
        
             
        
        
        
Answer:
There are eight types of vitamin B, that includes thiamin (Vitamin B1)
, riboflavin, niacin
, pantothenic acid
, biotin
, pyridoxine (vitamin B6 ), folate or folic acid, cyanocobalamin (vitamin B12).
Thiamin (vitamin B1) is responsible for glucose conversion into energy. Riboflavin helps in vision and skin health. Niacin functions to convert fat, carbohydrates and alcohol into energy. Pyridoxine (vitamin B6) and Pantothenic acid (B5) helps in the metabolism of carbohydrate and protein, to form brain chemicals and red blood cells. Biotin (B7) is responsible for amino acid and fat synthesis, energy metabolism, and glycogen synthesis. High biotin intake can contribute to raised blood cholesterol levels. Folate responsible in the formation of red blood cells and carry oxygen in the body,cell groth and DNA synthesis. cyanocobalamin (Vitamin B12) has multiple functions such as formation of red blood cells,to produce and maintain the myelin of nerve cells, and breakdoen of fat and amino acid to produce energy.
