Respiration
Transfers the energy in organic compounds (glucose) to make ATP
C6H12O6 + 6O2 ----- 6CO2 + 6H2O + ATP
Occurs in mitochondria Occurs in prokaryotic cell
membranes
What organisms undergo cellular organisms?

Cellular RespirationCellular Respiration
2 Types of Respiration
2 Types of Respiration
Aerobic Respiration: Requires oxygen to transfer the energy in glucose to ATP
Anaerobic Respiration: Does not require oxygen to transfer the energy in glucose to ATP
Aerobic Respiration: Requires oxygen to transfer the energy in glucose to ATP
Anaerobic Respiration: Does not require oxygen to transfer the energy in glucose to ATP
Two Stages of Cellular RespirationTwo Stages of Cellular Respiration
Cellular Respiration
Cellular Respiration
STAGE ONE- Breakdown Glucose –
primary fuel for respiration Breakdown of Glucose is
called Glycolysis Carbohydrates (starches,
sucrose) are broken down for energy (fats too)
Glycolysis makes pyruvate and uses two ATP molecules, but makes four ATP molecules

STAGE TWO- ATP production A. Pyruvate enters
mitochondria B. Goes through a series of
chemical reactions called the Kreb’s Cycle
Creates MORE ATP – 32 – 34 Molecules of ATP

When oxygen is present more ATP is produced then when it is not
When oxygen is absent small amounts of ATP are produced in a process called fermentation

Cellular RespirationCellular Respiration Lactic
Acid Fermentation
Lactic Acid Fermentation
Lactic Acid Fermentation: A. By some prokaryotes
and fungi used to produce foods like yogurt & cheese
Lactate can build up in muscles if it isn’t removed quick enough = sore muscles

Cellular RespirationCellular Respiration Alcoholic
Fermentation
Alcoholic Fermentation
Alcoholic Fermentation Pyruvate broken down to
ethanol (alcohol) Carried out by yeast to
make wine and beer Causes yeast to release
CO2 to make bread rise, carbonate alcohol

Aerobic vs. Anaerobic Respiration
Suppose you’re an organism that can carry out either aerobic respiration or anaerobic energy pathways. Which one would be more beneficial to you and why?
