Cellular Respiration

Question 1

This is a metabolic pathway that uses glucose to produce adenosine triphosphate.

Answer 1

Cellular Respiration

Question 2

Three stages of cellular respiration.

Answer 2

Glycolysis, Citric Acid Cycle/Krebs Cycle, Electron Transport Chain

Question 3

This takes place in the cytoplasm of the cell and does not require oxygen (anaerobic).

Answer 3

Glycolysis

Question 4

What is produced in glycolysis?

Answer 4

A small amount of ATP
and NADH.

Question 5

In glycolysis, a molecule of glucose is broken down into what?

Answer 5

Two molecules of pyruvate.

Question 6

NADH stands for?

Answer 6

Nicotinamide Adenine Dinucleotide + Hydrogen

Question 7

This occurs in the mitochondria,
and it is aerobic, requiring oxygen.

Answer 7

Krebs Cycle

Question 8

What is produced in the Krebs Cycle?

Answer 8

A small amount of ATP and more electron carriers (NADH and
FADH2.)

Question 9

FADH2 stands for?

Answer 9

Flavin Adenine Dinucleotide + 2 Hydrogen

Question 10

This takes place in the inner
mitochondrial membrane.

Answer 10

Electron Transport Chain

Question 11

This is the final electron acceptor in the electron transport chain.

Answer 11

Oxygen, which combines with electrons and protons to form water.

Question 12

This stage creates the most ATP in the three stages of cellular respiration.

Answer 12

Electron Transport Chain

Question 13

6 components of Electron Transport Chain.

Answer 13

1. Electron carriers
2. Complexes
3. Electron transfer
4. Proton gradient
5. ATP synthesis
6. Oxygen as the final electron acceptor

Question 14

What is the equation of cellular respiration?

Answer 14

C₆H₁₂O₆+6O₂ -> 6CO₂+6H₂O+ATP

Question 15

What does each part of the equation stand for?

C₆H₁₂O₆+6O₂ -> 6CO₂+6H₂O+ATP

Answer 15

C₆H₁₂O₆ is glucose, 6O₂ is oxygen, 6CO₂ is carbon dioxide, 6H₂O is water, and ATP is energy
