Harvesting Chemical Energy
ATP
Cellular Respiration
 Biochemical process that
__________________________________________________________________________________
__________________________________________________________________________________
The ________________________________ is temporarily stored in the ____________________. This energy is
_________________________________________________ in all organisms.
Photosynthesis allows respiration to occur
Photosynthesis
How does photosynthesis allow respiration to occur?
The products of photosynthesis allow respiration to happen! Photosynthesis gives organisms:
1. _________________________________
2. __________________________ (helps release stored energy)
Photosynthesis and Respiration (Both rely on each other)
Photosynthesis ______________ the ______________ __________________ in _______________________ and relseases
oxygen as a waste. BOTH plants and animals (including us) use glucose and oxygen for ______________________________
____________________________________.
 Photosynthesis uses the products of respiration!
 Respiration uses the products of photsynthesis!

Respiration Equation
 Respiration:

Photosynthesis
Carbon Dioxide + water + light energy  Glucose + Oxygen

Two Forms of Cellular Respiration
1. Aerobic Cellular Respiration:
2. Anaerobic Cellular Respiration:
What is the purpose of respiration?
What type of cellular respiration do you think is more efficient?
Aerobic Respiration
 Form of cellular respiration carried out by cells in the ______________________________________________.
o
Occurs in ___________________________
o
Purpose is to release the energy stored in organic molecules and form ATP (ready-to-use energy)
o
Uses oxygen to release the maximum amount of energy stored in organic food.
o
For this reason, aerobic respiration is much ___________ _____________________ at making ATP than anaerobic
respiration.

Why is all of this energy needed?
Anaerobic Cellular Respiration
 Form of cellular respiration carried out by cells in the absence of oxygen.
o
Occurs in cell mitochondria
o
Purpose is to release the energy stored in organic molecules and form ATP (ready-to-use energy)
o
Used by certain _____________________ and __________________ (fungi)
o
____________________ also use anaerobic cellular respiration
o
Process used to make _______________, ________________, baked goods, brewed goods and wines.
TWO TYPES
1. Alcohol fermentation
 Type of anaerobic respiration where ________________________ is produced as a product

Glucose  2ATP + Carbon Dioxide + ___________________________________

Certain fungi (yeasts) perform this… giving us beer and wine
Without mitochondria and anaerobic respiration… there would be no alcohol.
2. Lactic Acid fermentation
 Type of anaerobic respiration which produces ________________________ as one of its products

Glucose  2ATP + Carbon Dioxide + _________________________

In humans, during strenuous exercise, not enough ___________________ present in blood “oxygen debt”

Lactic acid accumulates in muscles; leads to ______________________ and pain
Both types of anaerobic respiration are considered inefficient. The end products of both (ethyl alcohol and lactic acid) contain
lots of energy that has not been effectively released for use by the cell.
