Why is cellular respiration considered an efficient process?

Answer 1

Glycolysis is the first step of cellular respiration.

Glycolysis produces much less ATP (2) than the combined total ATP of the rest of aerobic respiration (about another 30). The majority of ATP is produced by the electron transport chain. Cellular respiration is considered more efficient than glycolysis because it produces significantly more ATP. ATP stands for adenosine triphosphate.

Answer 2

Aerobic respiration produces 36-38 ATP whereas glycolysis makes 2 ATP.

During aerobic respiration Pyruvic acid is completely oxidized to CO2 and Water and all energy in it utilized while in anaerobic respiration a lot of energy is still present in lactic acid , alcohol or other products .

Answer 3

The 36 ATP molecules generated represent about 36 percent of the total energy of glucose. Means that the cell is more efficient at using food than the engine of a typical automobile is at burning gasoline. The remaining 64 percent is released as heat, that is why your body feels warmer after a vigorous exercise, and why your body temperature remains 37 degrees celcius day and night.

Answer 4

Cellular respiration is considered efficient because it extracts a high amount of energy from glucose molecules in the form of ATP. It involves a series of reactions that efficiently convert chemical energy from glucose into ATP, which is the cell's primary energy source. This process occurs in multiple steps, allowing for a controlled release of energy and maximizing the amount of ATP produced from each glucose molecule.

Answer 5

Because you get so many more glucose derived ATP from cellular respiration (36-38) than you do from glycolysis alone (2)
