• 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!

11
B. Location of Respiration

• In cytoplasm and mitochondria
• Mitochondrion membranes contain enzymes involved
  in respiration

• Foldings provide large surface area

12
C. Two Types of Respiration

• 1. Aerobic Respiration
• - Requires presence of oxygen
• 2. Anaerobic Respiration
• - No oxygen

13
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

15
Anaerobic Respiration- general info

• No oxygen available
• Ex sprinting
• Result?
• Makes ATP all through process of glycolysis!

16
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

17
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.

18
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

19
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.
