Intro to Cellular Respiration / Aerobic Respiration

storage

Glucose is good for ?, not as fuel → we use ATP instead for fuel

Fermentation

one way to convert glucose to ATP

• anaerobic

• makes 2 ATP

Aerobic Respiration

one way to convert glucose to ATP

• aerobic

• makes 36 ATP

NAD⁺ / NADH, FADH / FADH₂

Electron carriers in Cellular Respiration

OUT

In the ETC of Cellular Respiration, NADH / FADH₂ move high energy electrons to the ETC

• as electrons move down the ETC, H⁺ ions are pumped ? of the matrix to the inner membrane space

  • H⁺ diffuses back the opposite way through ATP Synthase making ATP

    • This is the opposite of the Light Reactions

Cristae

The electron transport chain in Cellular Respiration takes place in the ?

Glycolysis

1st step of Aerobic Cellular Respiration

• Splitting glucose into 2 (3-Carbon) pyruvate

• Takes place in cytosol

2 pyruvate

Glycolysis’s products

2, 4

Glycolysis uses ? ATP and produced ? ATP

• only small organisms can live off of this

O₂

What happens to pyruvate depends on the presence of ?

common ancestor

All living organisms utilize glycolysis, which is major evidence for a ?

Prep (Linking) Step

2nd step of aerobic respiration

• Moves reaction into the mitochondria

• Takes place in the matrix

Acetyl-CoA

In the Prep (Linking) Step Pyruvate is converted into ?

Krebs Cycle

3rd Step of Aerobic Cellular Respiration (aka Citric Acid Cycle)

• the point is to reduce the electron transporters (NAD⁺ / FADH) → a little ATP is made in the process (2)

• takes place in the matrix

3, 1

One cycle of the Krebs Cycle makes ? NADH and ? FADH₂

• more electron carriers → more electrons in ETC → more ATP produced
