ATP synthesization - Simple and complex lipids or carbohydrates are used to produce ATP through redox reactions. After the hydrolysis of complex carbohydrates, glucose and fructose are formed and the triglycerides are metabolized to form glycerol and fatty acids. ATP is then synthesized by oxidative phosphorylation and photophosphorylation during the energy production with in the living organisms. ATP production usually takes place in the mitochondria of the cell. The important pathways by which ATP is generated are glycolysis, the citric acid cycle (or the Kreb’s cycle), and the electron transport chain (or the oxidative phosphorylation pathway). In these three cycles of cellular respiration adenosine diphosphate (ADP) is converted to ATP and energy is released from molecules.
It is converted into Carbon dioxide which is given off as a waste product
Ans. (4). protein synthesis.
Protein synthesis can be defined as a process that involves formation of polypeptides or proteins by using information present in DNA. It is divided into two steps, transcription and translation.
During transcription, DNA is transcribed into mRNA and information present in DNA is transferred to mRNA as codons. Codons represent triplet of nucleotides and each codon codes for a specific codon.
Translation involves formation of protein, during which amino acids are added to the growing polypeptide chain with the help of codons.
The given diagram represents process of translation. Thus, the correct answer is option (4).
