Understanding the TCA Cycle

What is the primary focus of the TCA cycle discussed in this lesson?

• Electron Transport Chain

• Glycolysis

• TCA Cycle

• Photosynthesis

What is the main goal of the TCA cycle?

• To produce glucose

• To generate NADH and FADH2

• To break down fatty acids

• To synthesize proteins

Which molecule marks the first step in the TCA cycle?

• Pyruvate

• Oxaloacetate

• Acetal COA

• Citrate

During which step is the first NADH molecule produced in the TCA cycle?

• Suinate to Fumemerate

• Isocitrate to Alpha Ketoglutarate

• Citrate to Isocitrate

• Alpha Ketoglutarate to Suinal COA

What is the rate-limiting enzyme of the TCA cycle?

• Alpha Ketoglutarate Dehydrogenase

• Isocitrate Dehydrogenase

• Malate Dehydrogenase

• Citrate Synthase

Which molecule stimulates the TCA cycle?

• FADH2

• ADP

• NADH

• ATP

Which enzyme converts citrate to isocitrate?

• Isocitrate Dehydrogenase

• Fumarase

• Citrate Synthase

• Aconitase

Which step in the TCA cycle produces FADH2?

• Isocitrate to Alpha Ketoglutarate

• Citrate to Isocitrate

• Malate to Oxaloacetate

• Suinate to Fumemerate

Which of the following is NOT a product of the TCA cycle?

• Glucose

• FADH2

• NADH

• GTP

Which mnemonic helps remember where NADH is produced in the TCA cycle?
