Which of the following statements regarding the electron transport chain is false? transfer of electrons to the electron transport chain from nadh results in more atp synthesis than transfer of electrons from fadh2. each enzyme complex in the electron transport chain catalyzes the conversion of oxygen molecules to oxygen ions that eventually form water. oxidation of electron carriers within the electron transport chain results in the transport of protons across the inner mitochondrial membrane. the electron carriers within complex iv have a greater affinity for electrons than the electron carrier within complex iii.

the last statement is false.

Explanation: election affinity in complex 4 is less that is why there is Need of a mobile carrier cytochrome C. To increase the gradient between complex3 and 4

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
