1.

What is the basic chemical formula for cellular respiration?
- A.
  
  C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
- B.
  
  C6H12O6 + 6CO2 → 6H2O + 6O2 + ATP
- C.
  
  6H2O + 6O2 + ATP → 6CO2 + C6H12O6
Correct Answer
A. C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Explanation
Did you get the answer incorrect? Hint - Cellular respiration refers to what cells do to break up sugars. Also refer to the 'Cellular Respiration' page on the website.

What are the three main stages of cellular respiration?
- A.
  
  Glycolysis, Oxidation and Tricarboxylic Acid Cycle.
- B.
  
  Cellular Respiration, Oxidation and Reduction.
- C.
  
  Glycolysis, Tricarboxylic Acid Cycle and Oxidative Phosphorylation.
- D.
  
  Glycolysis, the Krebs Cycle, and Electron Transport Chain.
Correct Answer(s)
C. Glycolysis, Tricarboxylic Acid Cycle and Oxidative Phosphorylation.
D. Glycolysis, the Krebs Cycle, and Electron Transport Chain.

Explanation
Did you get the answer incorrect? Hint - The first stage of cellular respiration sees the breakdown of glucose, the second stage sees pyruvic acid and NADH used to make ATP and stage 3 sees NADH and FADH2 oxidised forming an H+ electron.

6.

Most ATP produced by oxidative phosphorylation is generated from the oxidation of NADH and ____________.

Correct Answer
FADH2

Explanation
Most ATP produced by oxidative phosphorylation is generated from the oxidation of NADH and FADH2. During oxidative phosphorylation, electrons from NADH and FADH2 are transferred through the electron transport chain, which generates a proton gradient across the inner mitochondrial membrane. This proton gradient is then used by ATP synthase to produce ATP. NADH and FADH2 are both electron carriers that donate electrons to the electron transport chain, but NADH generates more ATP than FADH2 because it enters the electron transport chain at an earlier stage, resulting in more proton pumping and ATP synthesis.

At the end of cellular respiration, a cell can yield a net total of 38 ATP molecules per glucose molecule.
- A.
  
  True
- B.
  
  False
Correct Answer
