Cellular Respiration

Question 1

What is Cellular Respiration Generally?

Answer 1

Glucose is turned into CO2 and H2O. Respiration harvests a lot of the energy. Occurs over multiple steps

Question 2

What is the order or things?

Answer 2

Glycolysis, Acetyl-CoA synthesis, Citric Acid cycle

Question 3

Glycolysis

Answer 3

Net two ATP per molecule of Glucose. Also two molecules of Pyruvate. Occurs in cytosol.

Question 4

Acetyl-CoA Synthesis

Answer 4

Pyruvate is turned into Acetyl-CoA. Plus you get two NADH

Question 5

Citric Acid Cycle

Answer 5

complex cyclical reactions. One glucose gets you 2 ATP, 6 NADH, 2 FADH2.

Question 6

Electron Transport Chain

Answer 6

Harvesting of free energy available from NADH and FADH2… roughly 28 ATP are gained from each glucose molecule.

Question 7

ATP Synthetase

Answer 7

One part rotates as protons flow through it, the other part uses this rotational energy to catalyze the synthesis of ATP.

Question 8

Where does this all take Place?

Answer 8

Glycolysis happens in the cytosol. Acetyl-CoA and Citric acid cycle happen in the matrix too.
