Cellular Respiration Ib
In the bonds of glucose, energy is placed. but isn’t useable. need to destroy the glucose in controlled way. Organic compounds used.
ATP is useable energy.
Active transport uses ATP, changes shape of proteins, going against conc. gradient, changes form atp to adp +Pi as one phosphate group lost.
Mitochondria double membrane inner membrane space ribosomes chloroplast
Mitochondrial matrix own DNA
Electron Transport Chain
Mitochondrial stuff occurs only if O2 is present
Also called Lactic acid fermentation
Products are lactic acid + 0 ATP
Oxidized molecule education products
Glycolysis in cytoplasm
(Glucose being substrate, substrate level phosphorylation occurs) Phosphorylation addition of phosphate
6 carbon glucose one phosphate added rearranged to fructose added second phosphate fructose 1,6- bisphosphate
2 ATPs 2 ADP deficit of 2 ATP
6 carbon divided to† two 3 carbon molecules: called G3P
G3P is oxidized ,positively charged which adds the phosphate to G3P.
NAD+ reduced to NADH + H+
P-o-o-o-P o-o-o (Pyruvate)
P is phosphates o is glucose
For every phosphate, remove phosphate using ADP to make ATP
2 pyruvates net gain of 2 ATPs
2 NADH + H+
Link Step (happens twice for each pyruvate)
Pyruvate transported into mitochondria
NAD+ oxidized pyruvate, coupled with, a decarboxylation (gets rid of a carbon) o-o-o ---> o-o (Aceytyl)
2-c combines with CoA to form Acetyl CoA
2 Redox and 2 Decarbon
Oxabocetate (4 carbon) combines with Acetyl CoA, CoA disappears --> 6 carbon (Citratade)
NAD+ --> NADH+H+; 5 carbon sugar happens, one CO2 leaves
