Which of the following is not a requirement for glycolysis?

• Oxygen
• ATP
• NAD⁺
• Glucose

Which is not part of the net products of Glycolysis?

• 2 ATP
• 2 NADH
• 2 Pyruvate
• 2 CO₂

Where does glycolysis occur?

• mitochondrial matrix
• cytoplasm
• inner membrane of mitochondria
• outer membrane of mitochondria

After the Krebs Cycle only a small portion of the energy of glucose has been converted to ATP. At this point the majority of usable energy is contained in

• NADH and FADH₂
• Carbon Dioxide 
• Acetyl-CoA
• Citrate

NADH and FADH₂ 

• carry electrons to the ETC.
• bind with Acetyl CoA.
• supply energy for the cell.
• make water.

Where does the Krebs Cycle take place?

• mitochondrial matrix

• mitochondrial inner membrane

• intermembrane space

• cellular cytoplasm

In the electron transport chain, Oxygen acts as...

• a carrier of electrons, passing electrons down the chain

• a reducing agent

• the final electron acceptor

• a coenzyme

When protons are pumped outside the matrix, across the inner membrane...

• water is made

• a concentration gradient of H⁺ ions (protons) is created

• NADH gets reduced

• CO₂ is produced
