Chapter 9 Review

What is the difference between oxidation and reduction in reference to redox reactions?

• Oxidation and reduction have no impact on the electron count in redox reactions.
• Oxidation involves the gain of electrons, while reduction involves the loss of electrons.
• Oxidation and reduction are interchangeable terms in redox reactions.
• Oxidation involves the loss of electrons, while reduction involves the gain of electrons.

What is the function of glycolysis?

• To break down glucose into pyruvate to produce ATP and NADH.
• To produce lipids from glucose
• To convert pyruvate into glucose
• To synthesize glucose from pyruvate

What is the function of the Citric acid Cycle?

• Converts proteins into lipids
• Synthesizes glucose from pyruvate

• Uses ATP to create proteins

• Generate energy through the oxidation of acetyl-CoA

What powers the ATP synthase to make ATP?

• Glucose

• Phospholipids

• ATP

• Proton gradient

This complex only functions under which conditions?

• a high proton gradient

• when NADP is reduced to NADPH

• when iions are evenly dispersed

• when clowns drive cars

How are fermentation and cellular respiration similar? How are they different?

• Fermentation and cellular respiration both involve the breakdown of glucose to produce energy, but fermentation does not require oxygen.
• Fermentation and cellular respiration both occur in plants only.
• Fermentation and cellular respiration have the same end products.
• Fermentation produces more ATP than cellular respiration.
