Goal B: Cellular Respiration Flashcards
What is Cellular Respiration
The process by which organisms (plants & animals) use Oxygen to break down glucose in the form of ATP.
What are the Inputs/Outputs of Cellular Respiration?
Inputs: Oxygen + Glucose
Outputs: ATP + H20 + CO2
Chemical Equation for Celluar Respiration
6O2+C6 H12 O6 –> 6CO2+6H2O+ATP
Where does Cellular Respiration Occur?
Cytoplasm and Mitochondria
Mitochondria
Where most Cellular Respiration occurs
(Krebs Cycle and ETC)
Steps of Celluar Respiration
1) Glycolysis
2) Krebs Cycle
3) Electron Transport Chain (ETC)
Glycolysis
Where? What? Produces?
Occurs in Cytoplasm
Glucose splits in 2 as Pyruvate
Produces ATP and NADH for step 3
Krebs Cycle
Where? What? Produces?
Occurs in Matrix of Mitochondria
Glucose fully breaks down
NADH/FADH2 molecules produced
Produces ATP and CO2
Electron Transport Chain (ETC)
Where? What? Produces?
Occurs in Inner Membrane of Mitochondria
Oxygen is used with electron-carrying molecules from steps 1 & 2 to make ATP
Produces: Lots of ATP and H20
Why do animals need to breathe
To get the Oxygen needed for CR!
How does breathing relate to CR
Breathing in: O2 for CR
Breathing out: CO2 (product of CR)
What are the different types of Cellular Respiration?
1) Aerobic
2) Anaerobic
What is Aerobic Respiration
CR that occurs in the presence of Oxygen
What is Anaerobic Respiration
CR that occurs when oxygen is low or not present
Plants/Fungi/Bacteria still need energy!
Reactants of CR
Glucose + Oxygen
