Question

question 17 put the steps of cellular respiration in order. 1. two molecules of pyruvate move into the mitochondria where they are converted into acetyl coa. more nadh is produced and co2 is released. 2. the electron transport chain, the nadh and fadh2 give up electrons, energy is released and captured as it moves from a high concentration to a low concentration. energy is used to produce about 32 - 34 atp. 3. glycolysis takes place in the cytoplasm and breaks down glucose to form two molecules of pyruvate. 2 atp are produced and nadh is saved for later. 4. citric acid/krebs cycle the carbons that are left from the initial glucose are oxidized, releasing more co2. nadh and fadh2 and 2 atp molecules are produced.

Explanation:

Cellular respiration steps in order: Glycolysis (cytoplasm, glucose → pyruvate), pyruvate → Acetyl CoA (mitochondria), Citric Acid Cycle (oxidizes carbons, produces NADH/FADH2/ATP), Electron Transport Chain (uses NADH/FADH2, produces ATP).

3, 1, 4, 2
