Cellular
Respiration
![Page 3: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/3.jpg)
GLYCOLYSIS
occurs in the cytoplasm of plant and animal cells
Anaerobic (does not require O2)
breaks glucose (a 6-C sugar) into 2 pyruvate molecules (2 3-C molecules)
Each step is catalyzed by a specific enzyme

![Page 5: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/5.jpg)
Step 1: ATP phosphorylates Glucose to G6P
![Page 6: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/6.jpg)
Step 2:G6P is rearranged to F6P
![Page 7: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/7.jpg)
Step 3:ATP phosphorylates F6P to F 1,6 BP
![Page 8: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/8.jpg)
Step 4:F 1,6 BP is split into DHAP & G3P
![Page 9: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/9.jpg)
Step 5:DHAP is immediately converted to G3P
![Page 10: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/10.jpg)
Step 6:2 G3P are converted to 2 BPG. H atoms reduce NAD+ to NADH
![Page 11: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/11.jpg)
Step 7:BPG is converted to 3PG. A high E phosphate on BPG phosphorylates ADP to ATP
![Page 12: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/12.jpg)
Step 8:3PG is rearranged to 2PG
![Page 13: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/13.jpg)
Step 9:2PG is converted to PEP by removing a water molecule
![Page 14: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/14.jpg)
Step 10:PEP is converted to pyruvate. A high E phosphate on PEP phosphorylates ADP to ATP
![Page 15: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/15.jpg)

PYRUVATE OXIDATION
![Page 17: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/17.jpg)
PYRUVATE OXIDATION
The 2 pyruvate molecules formed in glycolysis are transported through the 2 mitochondrial membranes, into the matrix
![Page 18: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/18.jpg)
PYRUVATE OXIDATION
Pyruvate undergoes oxidation A CO2 portion is removed
NAD+ is reduced by two H atoms to form NADH
Coenzyme A is attached to the remaining acetic acid portion (forming Acetyl-CoA)
![Page 19: A EROBIC C ELLULAR R ESPIRATION. GLYCOLYSIS STAGE 1: GLYCOLYSIS Cellular Respiration](https://reader036.vdocument.in/reader036/viewer/2022062408/56649f1e5503460f94c35a84/html5/thumbnails/19.jpg)
WHAT IS ACETYL-CO A
Can be used to produce fat or ATP
If the body needs E, it enters Krebs cycle
If the body does not need E – acetyl CoA is channelled into an anabolic path that synthesizes lipids.

KREB’S CYCLE
occurs in the mitochondrial matrix Acetyl-CoA is fed into the pathway
and the oxidation of the original C from glc is complete
It is a CYCLE! begins and ends with the same compound (oxaloacetate)
