Answer is: the oxidation number of oxygen must decrease.
Oxidizing agent is element (substance) that gain electrons in chemical reaction.
For example, balanced chemical reaction: C + O₂ → CO₂.
Oxygen change oxidation number from 0 to oxidation number -2 (reduction) and carbon change from 0 to +4 (oxidation)
Oxidation of a 24-carbon fatty acid would require ELEVEN (11) rounds of beta-oxidation and TWELVE (12) rounds of the Krebs cycle. It is part of cellular respiration.
<h3>The Krebs cycle and cellular respiration</h3>
Cellular respiration is a group of chemical reactions by which aerobic cells can produce ATP by using energy from foods.
Cellular respiration has three parts: glycolysis, the Krebs cycle (also called the acid citric cycle) and oxidative phosphorylation.
During the Krebs cycle, hydrogen atoms or electrons pass through a series of hydrogen/electron carriers.

Answer:
I think the total number of valence electrons in a water is 8.
Answer : The correct answer is a) an exothermic reaction that releases energy.
Combustion reaction is generally referred as burning or when hydrocarbon reaction with oxygen to produce carbon dioxide and water . Combustion reaction releases energy. Example :
CH₄ + O₂ → CO₂ + H₂O + Energy or heat .
The reaction which releases energy or heat are known as Exothermic reactions .
Since it says hot dogs and hamburgers are cooked means they are undergoing combustion chemical reaction and so they are exothermic reactions. So option a) an exothermic reaction which releases energy is correct .
Since hydrogen only has 1 electron it shares 1 with flourine to have a pair. It is single bonded.
