Question

1-6

discuss the use of ATP as the energy currency of the cell (include in your discussion the types of work performed by the cell) Discuss ATP synthesis and ATP hydrolysis: How do cells obtain the energy to synthesize ATP? Why do cells hydrolyze ATP? What do cells do with released energy obtained from the hydrolysis of ATP? discuss oxidation & reduction and the role of electron transfer in ATP synthesis discuss the role of NAD and FAD in electron transfer and discuss how the oxidation of NADH at the electron transport chain results in ATP synthesis discuss standard reduction potential and its relationship to electron donor, electron acceptor and exergonic reactions describe the role of enzymes in the catalysis of biological reactions include in the discussion substrate, product, active site, lock and key model, activation energy, enzyme substrate complex, and transition state complex, and steps of enzyme action)

Answer 1

ATP is known as adenosine triphosphate and it consists of molecule like carbon,hydrogen,oxygen,phosphorus.and it is also energy currency of cell, due to it donates phosphoryl groups to release energy, In the atp due to presence of adenine andribosyl groups they give additional attachments to enzymes,so it regulates enzymic activities.It release a high negetive gibbs free energy which can be used to drive many important biosynthetic reactions in metabolic pathways on hyrodlytic reaction.

ATP hydrolysis is a reverse process. in this hydrolysis reversible of ATP molecule to ADP molecule,the reversible reaction that combines ADP+Pi to regenerate ATP from ADP. where the ATP hydrolysis release energy, ATP synthesis that involve the transfer of electrons from the intermembrane space that through the inner membrane that back to matrix, those combination of two components provide sufficient energy for ATP made by the multienzyme is ATP synthesis.
