This should be most likely true
Answer:Voltage-gated channels open (activate) in response to changes in membrane potential because the electric field acts on the channel to change its protein conformation (or state). It is voltage-gated sodium (Na+) channels that initiate action potentials and voltage-gated K+ channels that cause them to end.
Answer:
a. New alpha- 1,6 linkages can only form if the branch has a free reducing end
b. The number of sites for enzyme action on a glycogen molecule is increased through alpha- 1,6 linkages
c. At least four glucose residues separate alpha-1,6 linkages
e. The reaction that forms alpha-1,6 linkages is catalyzed by a branching enzyme.
Explanation:
Glycogen i is the main storage polysaccharide in animals. It a homoplymer of (alpha-1-->4)-linked subunits of glucose molecules, with alpha-1--->6)-linked branches.
The alpha-1,6 branches are formed by the glycogen-branching enzyme which catalyzes the transfer of about 7 glucose residues from the non-reducing end of a glycogen branch having at least 11 residues to the C-6 hydroxyl group of a glucose residue which lies inside the same glycogen chain or another glycogen chain, thereby forming a new branch. This ensures that there are at least four glucose residues separating alpha-1,6 linkages.
The effect of branching is that it makes the glycogen molecule more soluble and also increases the number of non-reducing ends, thereby increasing the number of sites for the action of the enzymes glycogen phosphorylase and glycogen synthase.
Explanation:
As we know that chloride ion is halogen. So it has seven valence electrons in its valence shell. Hence it gains one electron from others during chemical reaction to be stable. So Chloride ion have a negative charge of -1.
Hope it will help :)❤
