Homework Answers
Answer :
Cellular respiration is the oxidation of organic compounds to extract energy.
An atom that losses electrons is oxidized and an atom accepting electrons is reduced .
NAD+ accepts a pair of electrons from the substrate along with a proton to form NADH.
Cells use enzyme-facilited redox rections to take energy from food sources and convert it to ATP.
Energy is released during each transfer of electrons in cellular respiration.

6. Cellular respiration depends on a series of REDOX reactions. In today's lab, and in class, we learned that we can think of oxidation and reduction in terms of electronegativity and electron density. During oxidation, the oxidized species loses electron density. During reduction, the reduced species gains electron density. a. Knowing that, label the following with oxidizing agent reducing agent, oxidized product, and reduced product. They are not balanced equations (1 point each blank; 8 points total). -C-H + O=...

Categorize the following: Aerobic respiration, Anaerobic respiration, Fermentation, None of these .Assume in all cases that these processes follow breakdown of glucose by glycolysis. Results in complete oxidation of glucose to CO2 Involves regeneration of reduced co-factors (e.g. regenerating NAD+ from NADH) Generates energy by substrate level phosphorylation only Generates ATP by oxidative phosphorylation Utilizes an electron transport chain Uses molecules such as NO3 - , SO4 2- , or Fe3+ as terminal electron acceptors Products include organic acids, alcohols,...
