Respiration in Cells (chapter 7)
Anaerobic - without oxygen
Fermentation
two strategies
different final acceptor (not oxygen) in electron transport chain
Nitrate (E.coli)
substrate-level phosphorylation (glycolysis)
lactate (muscle cells)
ethanol (yeast cells)
generate only 2 ATP
Aerobic - with oxygen
Cellular Respiration
4 Metabolic Pathways
Glycolysis
(cytosol)
Breakdown of Pyruvate
(mitochondrial matrix)
3.
Citric Acid Cycle / Krebs Cycle
(mitochondria)
Oxidative Phosphorylation
(mitochondria)
usually requires oxygen
Electron transport chain
releases high energy electrons
3 more items...
Phosphorylation by
ATP synthase
via Chemiosmosis
Net production:
30 - 34 ATP
Acetyl and CoA deattach
Acetyl attach to
oxaloacetate
to form
citrate
(aka citric acid)
series of steps release
2 CO2, 1 ATP, 3 NADH, and
1 FADH2
from 1 Acetyl CoA
1 more item...
Net production:
2 ATP, 6 NADH, 2 FADH2, 4 CO2 (removed)
broken down by
pyruvate dehydrogenase
2 CO2 produced but removed
2 Acetyl CoA & 2 NADH produced
Net production:
2 Acetyl CoA, 2 NADH, 2 CO2 (removed)
energy investment phase
cleavage phase
energy liberation phase
produces to
2 pyruvates, 2 NADH, 4 ATP
6 carbon molecule to
two
3 molecules of
glyceraldehyde-3-phosphate (G3P)
2 ATP to breakdown glucose to
fructose-6-phosphate
Net Production:
2 ATP, 2 NADH, 2 pyruvates
Chemical Formula: C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water)
definition
process of obtaining energy from organic molecules & releasing waste products
breakdown of glucose to produce ATP for energy
other molecules can also be used
carbohydrates ---> sugars
proteins ---> amino acids
fats ---> glycerol & fatty acids
