Cellular Respiration Notes
Video Notes – Cellular Respiration: Energy Transfer in Cells
_______________________ ________________________: the process that living
organisms use to turn food (organic compounds) into the energy they need for
survival
FOOD  ENERGY
Organic Compounds + Oxygen  Carbon Dioxide + Water + Energy
(carbs, lipids, proteins)
_________ (adenosine triphosphate): the form of energy used by all living things.
•
ATP is like a rechargeable battery
•
When ATP is charged and energized it has ___________ phosphates.
•
Energy is released when the weak bond between the last two phosphates
is broken- requiring a small input of energy, followed by the formation
of new bonds and the release of a larger amount of energy
•
This reaction changes ATP into ____________ – adenosine diphosphate,
which has 2 phosphates
Right - Page 1
•
ADP is like a rechargeable battery that has _______________ its charge
•
To recharge ADP to create ATP your body converts food into energy
through the process of ________________ _______________________.
Aerobic Cellular Respiration: a process that requires _______________________
to convert food into ATP
•
Makes ________________ of ATP
Anaerobic Cellular Respiration: a process that does ___________ require oxygen
to convert food into ATP
•
Makes very ________________ ATP
PowerPoint Notes
How is ATP made by living things?
•
By releasing the _______________________ energy stored in food to
convert ADP back into ATP
•
Two possibilities depending on whether oxygen (O2) is needed or not:
1. Fermentation: does not require oxygen (______________________)
2. Cellular Respiration: requires oxygen (____________________)
Fermentation
•
Does not require oxygen (anaerobic)
•
Occurs in the ______________________ of cells
•
________________________ breaks down glucose to produce 2 ATP
•
Two common types:
1. __________________fermentation
2. _______________________ __________________fermentation
1. Alcohol fermentation
•
Glucose is broken down into ______________________________
and carbon dioxide, releasing enough energy to create 2 ATP
C6H12O6  2 C2H5OH + 2 CO2 + 2 ATP
glucose  ethanol + carbon dioxide + energy (heat + ATP)
•

Example: yeast causing bread to _________________
2. Lactic Acid Fermentation
•
Glucose is broken down into ____________________ ___________,
releasing enough energy to create 2 ATP
C6H12O6  2 C3H6O3 + 2 ATP
glucose  lactic acid + energy (heat + ATP)
•
Examples:
▫ Occurs in your __________________during rapid exercise
▫ Used in the dairy industry to make _____________________
and _______________________
Cellular Respiration
•
Requires oxygen (aerobic)
•
Occurs within the _________________________ and
_________________________ of your cells
•
_____________________ breaks down glucose in the presence of oxygen,
releasing enough energy to produce up to 38 ATP
C6H12O6 + 6 O2  6 CO2 + 6 H2O + 38 ATP
glucose + oxygen  carbon dioxide + water + energy (heat + ATP)
