Chapter 9: Cellular Respiration Flashcards
Where does the energy you need to survive come from
OM store energy in their chemical bonds
loss of electrons from a substance
oxidation
gain of electrons
reduction
reducing agent
e donor
oxidizing agent
e acceptor
Oxidation of glucose and reduction of oxygen
cellular respiration
what does nah+ form
nadh
general equation for cellular respiration
Carbohydrate (glucose) + oxygen —-> Carbon dioxide + water +energy (ATP) + heat
C6H12O6 + O2 —–> CO2 + H2O + 38 ATP + heat
catabolic pathways in cellular respiration
- Glycolysis
- Kreb’s Cycle
- Electron Transport Chain/Oxidative phosphorylation
where does glycolysis occur?
in cytosol
what does Glycolysis do?
breaks down glucose into 2 pyruvate molecules
where does the Kreb’s Cycle occur?
mitochondrial matrix
what is another name for the Kreb’s Cycle
Citrus Acid Cycle
what does the Kreb’s cycle do
decomposes pyruvate molecules to CO2
what does glycolysis produce
- 4 ATP’s produced = 2 NET ATP’s, known as
substrate-level phosphorylation - 2 NADH produced (contributes to ETC)
- 2 Pyruvate molecules produced (enters Kreb’s
Cycle) - 2 H2O produced
