Detailed explanation-1: -The products of cellular respiration are carbon dioxide, ATP, and water. During the production of acetyl-CoA from pyruvate, two carbon dioxide are formed. An additional four carbon dioxide are formed during the Krebs cycle.

Detailed explanation-2: -Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

Detailed explanation-3: -In respiration, the by-products are water and carbon dioxide molecules produced by the breakdown of carbohydrates.

Detailed explanation-4: -As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.

Detailed explanation-5: -This is a balanced equation of the cellular respiration of glucose. A glucose molecule combines with 6 oxygen molecules, producing 6 molecules of water, 6 molecules of water and ATP.
