Answer:
The correct answer will be- in coupled and coordinated manner.
Step-by-step explanation:
Cellular respiration is a complex process which involves the breakdown of the sugar molecule to provide energy in the form of ATP. The process takes place in the four stages: Glycolysis, Krebs cycle, link reaction, Krebs cycle and the electron transport chain.
These stages are interlinked to each other as the product and intermediates of one set of reaction act as a substrate to another set of reactions like the pyruvate of glycolysis acts as a substrate in the link reaction. Also, the NADH formed in glycolysis and Krebs cycle is used in the electron transport chain.
Thus, in a coupled and coordinated manner is the correct answer.
