Transcript Cellular Respiration and ATP

Biology Honors
Mrs. Cannavino
Write the formula for cellular
respiration
• Label the reactants (inputs)
• Label the products (outputs)
• Circle the purpose of this process!!
• ____ + ____
____ + ____+ ____
Why does life depend on cellular
respiration?
• Cells can’t use
glucose as it is,
must have ATP to
function
• This includes plant
cells!
• ALL cells must
go through
cellular
respiration
The Mitochondrion
• What’s the function?
• What do we call this process?
CELLULAR RESPIRATION
• What do we call the energy produced|?
ATP
• What organic molecule needs to be broken
down in order to get this energy?
GLUCOSE
Cristae
Anaerobic = NO OXYGEN
• Glucose is partially broken into lactic
acid or ethanol (ethyl alcohol)
• Small amount of ATP produced
• Alcoholic fermentation—occurs in
plants/bacteria/fungi
• Lactic acid fermentation—occurs in
animals/bacteria
– Ex: lactic acid builds up in muscles,
causes pH changes—hurts
ATP
• Adenosine triphosphate
• Molecule that is usable energy for cells
• Energy is found in bonds between phosphate
groups
ATP = Life’s Battery
• ATP is a rechargeable
molecule
• Energy releasing
reaction:
– ATP loses a P
– Adenosine diphosphate is
left (ADP)
– Energy is released for
cellular use
• Energy storing reaction:
– P is reattached to ADP
using energy from food
– ATP is made again
– Energy is stored for next
time cell needs it
