ATP is produced during the process of cellular respiration. Which is the order of the steps of cellular respiration? (A) Krebs c
ycle ® Calvin cycle ® electron transport chain(B) electron transport chain ® Krebs cycle ® glycolysis(C) glycolysis ® Krebs cycle ® electron transport chain(D) Calvin cycle ® electron transport chain ® glycolysis
Answer: C- glycolysis, krebs cycle, electron transport chain.
Explanation: Glycolysis is a catabolic reaction that comprises of series of steps that breaks down food to give off energy in a form of ATP. Pyruvate is the product of glycolysis together with two ATP molecules. Pyruvate is further broken down by joining the krebs cycle and finally the electron transport chain that transfer electrons using the redox reaction, to reduce NADH to NAD + H and FADH to FAD, creating the final product i.e ATP, Overall one glucose molecule gives 38 ATP molecules in aerobic respiration.
The term population refers to all members of a given species in a particular habitat at a particular time without taking into account abiotic factors. For example a population of lions in Tsavo National Park.
