What is the space between the inner and outer membrane of a mitochondrion called?

1

Where does the Krebs cycle take place in the mitochondrion?

1

In which part of the mitochondrion does the electron transport stage of cellular respiration occur?

CK12 2.27
1

Where does the first stage of cellular respiration, glycolysis, occur?

1

Does glycolysis require oxygen?

1

Why is glycolysis considered the most primitive pathway for making ATP?

1

Which of these bacteria can survive in the presence of oxygen?

1

What does the term glycolysis mean?

1

What molecules are produced from glucose in glycolysis?

1

In glycolysis, glucose is split into two pyruvate molecules. This releases energy, which is transferred to ATP. How many net ATP molecules are made during this stage of cellular respiration?

What kickstarts the Krebs cycle?

1

How many carbon atoms make up citric acid?

1

What is the product of reaction between pyruvic acid and CoA?

1

What does the third carbon from pyruvic acid combine with to form CO2?

1

What does the Krebs cycle produce?

1

What is another name for the Krebs cycle?

1

What happens to the original glucose molecule during the Krebs Cycle?

1

How many ATP molecules are formed after two Krebs Cycle turns (including from glycolysis)?

1

Which energy-carrier molecules are produced during the Krebs Cycle?

1

What happens to the carbon atoms of the original glucose molecule during the Krebs Cycle?

1

Where on the mitochondrion do the electron transport chains reside?

1

What happens to high-energy electrons transported along the chains?

1

What is used to pump hydrogen ions across the inner membrane during cellular respiration?

1

From where to where are hydrogen ions pumped during cellular respiration?

1

What creates a greater concentration of hydrogen ions in the intermembrane space?

1

What is the role of ATP synthase in the process of ATP production?
