Fuction of Cell Respiration?
|
Process of extracting the stored energy from glucose to form ATP (from ADP and Pi).
|
|
|
Chemical equation describing Respiration
|
C6H12O6+6O2-->6CO2+6H2O + energy
|
|
|
Aerobic Respiration
|
Respiration in the presence if O2.
1.gylcolysis 2.kreb cycle 3.oxidative phosphorylation |
|
|
Glycolysis
|
Cytoplasm
The decomposition of glucose to pyruvate. -9 intermediate products formed -Mg are cofactors that promote enzyme activity 1. Glucose forms 2PGAL (using 2 ATP) 2. 2 NAD and 4 ADP are used to convert 2PGAL to 2 Pyruvate -----------2 NADH & 4 ATP are produced |
|
|
Post Glycolysis+ Pre Kreb CYCle
|
Inner Mitochondrial Matrix
1. Pyruvate combines with coenzyme A to produce to acetyl CoA -------Produces 1NADH and 1 CO2 (x2) |
|
|
Kreb Cycle
|
Inner Mitochondrial Matrix
1.Acetyl CoA combines with OAA to form citric acid --------3 NADH. 1FADH2, 1 ATP, 2 CO2 (X2) |
|
|
Oxidative Phosphorylation
|
Mitochondrial Cristae
Process of extracting ATP form coenzymes NADH and FADH2 1. NADH/FADH2 is broken down to NAD/FAD +H+2e 2. Eelctrons from both pass alon an electron transport chian form one carrier protein (cyctocomes) to another, losing energy at each step. ---------the last electron acceptor is oxygen. .5O2 accetps the 2 electronds, together with 2 H, formes water . -NADH-->3 ATP -FADH2-->2 ATP |

Summary of Products in Aerobic Respiration
|
Glycoysis
-2 ADP -2 ATP -2 NADH-->4ATP -2 Pyruvate Pre Kreb -2 NADH -->6 ATP -2 CO2 -2 Acetyl CoA Kreb Cycle -6 NADH2 -2 FADH2 -2 ATP -4 CO2 Oxidative Phosphorylation -22 ATP -H20 |
|
|
PGAL (glyceride 3 phosphate)
|
Calvin Cycle
-->6 RuBP (ribulose bisphosphate) --> 1 glucose Glycolysis --> 2pyruvate |
|
|
Alcholic fermentation
|
In plants, functi, bacteria
1. 2 pyruvate from glycolysis convert into 2 acetaldehyde --------2 CO2 formed 2. 2 acetaldehyde convert to 2 ethanol ----2NAD+ formed(recycled in glycolysis: NADH from glycolysis) |
|
|
Lactic acid Fermentation
|
In animals
1. 2 pyruvate from glycolysis convert to 2 lactate ------NAD+ formed (recycled into glycolysis: NADH from glycolysis) |
|
|
Main purpose of fermentation
|
To get rid NADH or NAD+ and guse it in glycolysis for atleast 2 ATP. With no oxygen NAD+ is converted into NADH and a high accumulation of NADH stops both glycolysis and Krep cycle and the cell soon dies.
