Cellular Respiration

GLYCOLYSIS The breaking down of Glucose

Glucose (C6H12O6) but we are focused on the 6 Carbon

Breaks up the Carbon into 2 sets of 3 Carbon, but each has a Phosphate

INVESTMENT PHASE

Investment phase Uses 2 ATP's

C- C- C- C- C- C

P- C- C- C (PGAL)

In the Payoff Phase, the 2 PGALs are turned into Pyruvate

P- C- C- C (PGAL)

PAYOFF PHASE

C- C- C (Pyruvates), 2 ATP's are created, and 2 NADH's are created

P- C- C- C are changed to C- C- C

C- C- C (Pyruvates), 2 ATP's are created, and 2 NADH's are created

P- C- C- C are changed to C- C- C

We use 2 ATP's in Glycolysis, and end up making 2 ATP's at the end, Glycolysis also makes 2 NAD+'s into 2 NADH's, and 2 Pyruvate. (This all happens in the Cytoplasm

After we are left with the 2 Pyruvate, 2 NADH, and 2 ATP it starts the Krebs/ Citric Acid Cycle

Krebs / Citric Acid Cycle

Takes place inside the Mitochondria. When you do the Krebs cycle once it creates 8 NADH's, 2 ATP, and 2 FADH2.

We start off with the 2 Pyruvate, which are not ready for the Krebs cycle

Pyruvate C- C- C

Pyruvate C- C- C

Acetyl CoA, 2 Carbon C- C

Pyruvate Oxidation

During Pyruvate Oxidation it takes one carbon away from the Pyruvate, and it also reduces NADH to Nad+

Acetyl CoA, 2 Carbon C- C

Pyruvate Oxidation

During Pyruvate Oxidation it takes one carbon away from the Pyruvate, and it also reduces NADH to NAD+

After Pyruvate Oxidation we are left with 2 Carbon, which are Acetyl CoA

HERE THE KREBS CYCLE OFFICIALLY STARTS

Forms Citrate or Citric Acid which has 6 Carbons (C- C- C- C- C- C)

ENZYME CATALYZED REACTION

After being Catalyzed by Enzymes the Acetyl CoA merges with Oxoloacetic Acid which has 4 Carbons

Forms Citrate or Citric Acid which has 6 Carbons (C- C- C- C- C- C)

ENZYME CATALYZED REACTION

After being Catalyzed by Enzymes the Acetyl CoA merges with Oxoloacetic Acid which has 4 Carbons

After the Enzyme Catalyzed Reaction, we are left with Citric Acid which has 6 Carbons

After Oxidation the starting Pyruvate also get oxidized and one carbon is taken, making another CO2

We are left with CO2

OXIDATION

The Citrate is Oxidized and and 1 Carbon are taken out which leaves us with CO2

We are left with CO2

OXIDATION

The Citrate is Oxidized and and 1 Carbon are taken out which leaves us with CO2

We are left with CO2, FADH2, and more NADH, and we start again from the ENZYME CATALYZED REACTION

We are left with CO2, FADH2, and more NADH, and we start again from the ENZYME CATALYZED REACTION

After the NAD+'s turn to NADH's, and the FAD's turn to FADH's the whole process starts again from the ENZYME CATALYZED REACTION section. Which is why it is called a cycle.

More NAD+ turns into NADH

FAD's turn into FADH2

More NAD+ turns into NADH

FAD's turn into FADH2
