Explanation:
1.The ester bond between the alpha-phosphate and the ribose sugar in AMP is not a high energy bond.
2.When acetylcholine is released in excess it leads to synaptic fatigue. Synaptic fatigue occurs when there is a drastic decrease in the postsynaptic response.
3.Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals and fungi.
4.The polysaccharide structure represents the main storage form of glucose in the body. Glycogen is a branched biopolymer consisting of linear chains of glucose residues with further chains branching off every 10 glucoses or so.
5.Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.
7.When a cell is put in a higher solute concentration the solute movement is seen from inside to outside the cell which results into the contraction of the cell.
