N7.2 Breaking Down Nutrients for Energy​

Where does glycolysis take place in cells?

• Cytosol

• Mitochondrion
• Endoplasmic Reticulum
• Ribosomes

Glycolysis results in the net gain of:

• 2 ATP
• 4 ATP
• 4 NADH
• 2 Acetyl CoA

Which of the following is not a requirement for glycolysis?

• Oxygen
• ATP
• NAD⁺
• Glucose

What is the function of NAD+?

• It absorbs light
• It is an electron carrier
• It is a light-reflecting pigment
• It acts as long-term energy storage

In glycolysis, glucose is converted into two molecules of _____. 

• citric acid
• oxaloacetic acid
• pyruvic acid
• Acetyl CoA

Which is not a waste product of cellular respiration?

• Water
• Heat
• Carbon Dioxide
• Oxygen

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy
• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O
• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy
• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

Which molecule isn't an energy carrier?

• FADH₂
• NADH
• oxygen
• ATP

In this stage of cellular respiration, CO2 and NADH are made as pyruvate is converted into Acetyl COA

• Glycolysis
• Pyruvate conversion

• Krebs cycle
• ETC
• Fermentation

If oxygen is present, pyruvic acid molecules molecules enter the

• mitochondria
• cytoplasm
• cell membrane
• golgi apparatus
