RESPIRATION
What do wood, a marshmallow
and gasoline all have in common?
They all have stored chemical energy
that can be used for energy!!!!
I. Ultimate Source
 Autotrophs


A. Get their food: by photosynthesis
B. Get energy by cell respiration!
 Heterotrophs


A. Get their food: by consuming other
organisms
B. Get energy by cell respiration!

II. Cellular Respiration
A. PURPOSE: chemical process that converts
the chemical energy stored in food into ATP
 ATP is main energy supply of living
organisms!
B. Location of Respiration
 In cytoplasm and mitochondria
 Mitochondrion membranes contain enzymes
involved in respiration
 Foldings provide large
surface area
C. Two Types of Respiration
1. Aerobic Respiration
- Requires presence of oxygen
2. Anaerobic Respiration
- No oxygen
1. Cellular Respiration
i. Most cells do this (eukaryotes: most plants
and animal cells)
Aerobic process- REQUIRES OXYGEN!!
ii. Number of ATP produced: 36 ATP
Anaerobic Respiration- general info
 No oxygen available
 Ex: sprinting
 Result?
 Makes ATP all through process of glycolysis!
2. Alcoholic Fermentation
i. Type of cells: Yeast cells, some bacteria

Anaerobic- NO oxygen!
ii. Equation:
C6H12O6  2 Alcohol + 2 CO2 + 2 ATP

Ex: beer, wine, bread
iii. Number of
ATP produced?
2 ATP
Alcoholic Fermentation:
the process performed by yeast and some
bacteria to convert sugar into ATP when there
is no oxygen present. This is a TYPE of
anaerobic respiration. The products are
alcohol, CO2, and ATP.
3. Lactic Acid Fermentation
i. Type of Cells: Muscle cells, fungi, bacteria

Anaerobic- NO oxygen!
ii. Equation:
C6H12O6  Lactic Acid + 2 ATP

Ex: cheese, yogurt
iii. Number of
ATP produced?
2 ATP
Lactic Acid Fermentation
 The process performed by bacteria and by
HUMAN muscle cells to convert glucose into
ATP energy in the absence of oxygen. The
products are Lactic Acid and ATP.
