Answer #1

The carbondioxide we exhale is originating from

Answer : Lost in the TCA / citric acid cycle.

TCA cycle is a series of chemical reactions in which CO2 is released as a waste product from oxidation of acetylCoA .one turn of citric acid cycle produces two carbondioxidide molecules .

    The electron transport chain consists of protein complexes embedded in the inner mitochondrial membrane, where it generat a proton gradient by a series of oxidation-reduction, or redox, reactions. Although all of the stages of cellular respiration (glycolysis, the citric acid cycle, and the electron transport chain) are necessary for life, the electron transport chain is sometimes called the most important stage. First complete the sentence, then answer the question. The electron transport chain uses the transfer of protons between protein...

    Can someone reword this for me? Please and thank you! Cellular respiration is a process that converts energy from food molecules into the energy of ATP. It involves three stages that occur in the cytoplasm of cells and in the mitochondria. One of the three stages is the citric acid cycle which is a series of reactions that generates reduced electron carriers that transport electrons to the electron transport chain. Since the primary function of the mitochondria is to produce...
