Which does the electron transport chain do during cellular respiration?
A. Provides energy for pumping of hydrogen ions
B. Makes more energy carriers for respiration
C. Breaks down glucose into pyruvate molecules
D. Uses carbon dioxide and water to make glucose

During this process electrons are exchanged between molecules, which creates a chemical gradient that allows for the production of ATP. The most vital part of this process is the electron transport chain, which produces more ATP than any other part of cellular respiration.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
