Cellular Respiration
Defined as:
__________________________________________________________________________________________
__________________________________________________________________________________________
Location: __________________________________________________________________________________
Two types:
1. Aerobic = ____________________
2. Anaerobic = _____________________
Three Processes in Aerobic Respiration:
1. Glycolysis= ___________________________________________________________________
2. Kreb’s Cycle = _________________________________________________________________
3. Electron Transport Chain= _______________________________________________________
Equation for Cellular Respiration:
1. Glycolysis (Glyco = _____________, Lysis = _______________)
• Occurs with or without _____________
• Splits ______________ into two 3 carbon molecules called ______________________
•
Produces 2 _____________ and 2 _______________

2. Kreb’s Cycle
• _________________ is broken down
into __________ molecules
• Produces 2 more _________, several
_________ and __________
molecules (more school buses for eand H+)
Highlight all the
products of the
Kreb’s cycle
3. Electron Transport Chain (ETC)
• _________________ from NADH and
FADH2 pass down a chain of molecules
• Energy released used to pump H+ into intermembrane space
• H+ ions _______________ back into matrix through ATP synthase
• Yields ______________ per glucose

Why do we need O2??
• At end of __________, e- “caught” by ___________ which combines with H+, making ___________
• No _________ means _________ has nowhere to go
• ETC backs up with _________________
• Respiration stops = _____________
What happens when there is no O2??
• __________________________________________________________
• Occurs after ___________________
• Regenerates empty ___________ so that _________________ can continue
• Two types:
1. _________________________________________
• In plants, fungi
2. _________________________________________
• In animals
1. Alcohol Fermentation
• _____________________________________________________________________________
• Produces alcohol
• ___________ produced by yeast makes bread rise
2. Lactic Acid Fermentation
• _____________________________________________________________________________
• Creates burning sensation in muscles during intense exercise due to __________________________
