Question 1.
What is the main product of cellular respiration?
Show hintHide hint
Think about what glucose is converted into in the presence of oxygen.
Question 2.
What role do cofactors like NADH and FADH2 play in metabolism?
Show hintHide hint
Consider what happens in redox reactions.
3Question 3.
What is oxidized during cellular respiration?
- Oxygen
- Water
- Glucose
Show hintHide hint
Think about what happens to glucose during this process.
4Question 4.
True or False: NADH is the oxidized form of the coenzyme.
- True
- False
Show hintHide hint
Focus on the electron transfer states.
Question 5.
Calculate the change in Gibbs Free Energy (ΔG) for a reaction involving the oxidation of glucose, given the standard cell potential (E°) is +1.1 V and two moles of electrons are involved.
Show hintHide hint
Remember to substitute n with the number of moles of electrons transferred.
Question 6.
Explain the flow of electrons in cellular respiration is coupled with ATP synthesis. How does this relate to the proton gradient?
Show hintHide hint
Consider how the electron transport chain is structured and its purpose.
