What is the most common way humans store carbohydrate energy

            Carbohydrate is the first source of energy to human body. Glucose is the simple unit of carbohydrate which is used in respiration and produce ATP. When we eat food that contain carbohydrate, it convert into sugar units that are absorbed in small intestine. From here these sugar units travel to liver through blood where excess sugar is stored in the form of glycogen. When the body need energy this glycogen is converted to sugar through glucagon hormone and is used in respiration to produce ATP, which is necessary for  the activities of humans.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
