Overview
Glycolysis
Fermentation
Krebs Cycle
Electron Transport
100
What is cellular respiration?
Breaking down sugar (food) molecules to release the energy they contain.
100
Where does glycolyis take place?
cytoplasm
100
When does fermentation occur?
If no oxygen is present.
100
Where does the Krebs Cycle occur?
Inside mitochondria
100
Where is the electron transport chain found?
Membrane of mitochondria
200
What types of organisms go through cellular respiration?
all organisms
200
What are the reactants of glycolysis?
glucose, NAD+, ADP
200
DOUBLE JEOPARDY!!!!! Where does lactic acid fermentation occur?
muscle cells
200
What are the reactants of Krebs cycle?
pyruvic acid, NAD+, FAD, and ADP
200
What are the reactants of the Electron Transport Chain?
NADH, FADH2, and O2
300
DOUBLE JEOPARDY!!!!! How are photosynthesis and cellular respiration related?
They are almost opposites. Products of photosynthesis are reactants of cellular respiration.
300
What are the products of glycolysis?
pyruvic acid, NADH, ATP
300
Name an organism that carries out alcoholic fermentation.
yeast
300
What are the products of Krebs cycle?
CO2, NADH, FADH2, ATP
300
What are the products of the Electron Transport Chain?
H20, ATP, NAD+, and FAD
400
What is the equation for cellular respiration?
6 O2 + C6H12O6 => 6 CO2 + 6 H20 + ATP
400
If oxygen is present, what process follows glycolysis? If oxygen isn't present, what process follows glycolysis?
fermentation; Krebs Cycle (cellular respiration)
400
During which activity would your body carry out lactic acid fermentation- pedaling your bike quickly up a big hill or jogging around a track? Why?
pedaling your bike; muscles are working hard and using up oxygen
400
DOUBLE JEOPARDY!!!! How many NADH, ATP, and FADH2 molecules are formed in one turn of the Krebs cycle (for one molecule of pyruvic acid)?
4 NADH 1 FADH2 1 ATP
400
How is water formed in the electron transport chain?
Oxygen accepts electrons from the electron transport chain and joins with 2 H+ ions.
500
How many ATP are formed in cellular respiration?
36
500
Where does the NADH produced in glycolysis go?
Electron transport chain
500
Why is it important for fermentation to follow glycolysis?
So that NAD+ can be regenerated and glycolysis can continue, allowing more ATP to be produced
500
Where do the NADH and FADH2 from Krebs cycle go?
Electron Transport Chain
500
How is ATP made in the electron transport chain?
H+ ions from intermembrane space flow back through ATP Synthase, which spins and converts ADP to ATP
