Cellular Respiration Flashcards
produce ATP energy through the process of aerobic cellular respiration
mitochondria
the process of breaking down glucose in many steps
Cellular Respiration
releases energy!
Cellular Respiration
GLUCOSE =
cellular fuel
ATP
energy transport molecule
first step in cellular respiration
Glycolysis
glucose is broken down into 3-carbon pieces (each piece is called pyruvate)
Glycolysis
produces 2 ATP molecules
Glycolysis
takes place in the cytoplasm, outside of the mitochondria
Glycolysis
does not require oxygen
Glycolysis
pyruvate is coverted to acetyl CoA
Citric Acid Cycle (Kreb’s Cycle)
3-carbon pieces are broken down
Citric Acid Cycle (Kreb’s Cycle)
takes place in the center of mitochondria
Citric Acid Cycle (Kreb’s Cycle)
requires oxygen
Citric Acid Cycle (Kreb’s Cycle)
two more ATP molecules are produced
CO2 is a ____________
waste product
hydrogens are broken off and picked up by ___________
hydrogen carriers:
second step in cellular respiration
Citric Acid Cycle (Kreb’s Cycle)
third step in cellular respiration
Electron Transport System (Oxidative Phosphorylation )
electrons from hydrogen are passed along a system of enzymes within the mitochondria producing ___________ molecules of ATP
30-34 more molecules of ATP!!!!
H2O is a _____________
waste product
hydrogen carriers NADH and FADH2 (from Citric Acid Cycle) enter the electron transport system within mitochondrial membranes
Electron Transport System (Oxidative Phosphorylation )
requires oxygen
Electron Transport System (Oxidative Phosphorylation )
mitochondria produce ATP energy through the process of ____________
aerobic cellular respiration
