Question

question 30
during which phase of cellular respiration is the majority of atp formed?
a the krebs cycle
b glycolysis
c processing of pyruvic acid for the krebs cycle
d all phases produce the same number of atp molecules.
e electron transport system

Explanation:

Cellular respiration has three main stages: glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis produces a small amount of ATP (2 net ATP per glucose). The processing of pyruvic acid for the Krebs cycle (pyruvate oxidation) does not produce ATP directly. The Krebs cycle (per glucose) produces 2 ATP. The electron transport system (ETS) is where the majority of ATP is formed. As electrons move through the ETS and protons are pumped to create a gradient, ATP synthase uses this proton - motive force to produce a large amount of ATP (about 28 - 32 ATP per glucose).

Answer:

E. Electron transport system
