Ameba Sisters Cellular Respiration Quiz

What is the energy currency needed by cells?

• ATP

• ADP

• NADH

• FADH2

Answer explanation

ATP is the energy currency needed by cells. It is a high-energy molecule that provides energy for cellular processes. ATP is synthesized through cellular respiration and is used to power various cellular activities.

Which type of cells have membrane-bound organelles?

• Both prokaryotic and eukaryotic cells

• Eukaryotic cells

• Neither prokaryotic nor eukaryotic cells

• Prokaryotic cells

Answer explanation

Eukaryotic cells have membrane-bound organelles, distinguishing them from prokaryotic cells.

Where does glycolysis occur?

• Endoplasmic reticulum

• Cytoplasm

• Mitochondria

• Nucleus

Answer explanation

Glycolysis occurs in the cytoplasm. It is the process of breaking down glucose to produce energy. The cytoplasm is the location where this metabolic pathway takes place.

What is the net yield of glycolysis?

• 2 acetyl CoA and 2 NADH

• 2 FADH2 and 2 NADH

• 2 pyruvate and 2 ATP molecules

• 2 ATP and 6 NADH

Which step of aerobic cellular respiration requires oxygen?

• Krebs Cycle

• Glycolysis

• Chemiosmosis

• Electron transport chain

What is the final product of the electron transport chain?

• Glucose

• Water

• Carbon dioxide

• ATP

Answer explanation

The final product of the electron transport chain is water. During this process, electrons combine with oxygen to form water, generating energy in the form of ATP.

How many ATP molecules are produced in the Krebs Cycle?

• 2

• 6

• 26-34

• 30-38

What is the purpose of fermentation?

• To produce glucose

• To break down glucose

• To make ATP without oxygen

• To generate a proton gradient

Answer explanation

Fermentation allows ATP production without oxygen, making it essential for anaerobic organisms and during low oxygen conditions.

What can block ATP production in the electron transport chain?

• Glucose

• ADP

• Water

• Cyanide

What is the main goal of aerobic cellular respiration?

• To transport electrons

• To make glucose

• To generate ATP

• To produce carbon dioxide
