Cellular Respiration Chapter 9 Slide 2 Cellular Respiration
(Opposite of Photosynthesis) Overall equation: C 6 H 12 O 6 + 6O 2
6CO 2 + 6H 2 O + energy (glucose + oxygen) (carbon dioxide + water)
Releases energy by breaking down glucose Occurs in all cells in all
living things (Plants go through cellular respiration at night) In
the presence of oxygen, cellular respiration produces a total of 36
ATP molecules per glucose. Slide 3 2 Types of Cellular Respiration
1. Aerobic respiration does require oxygen Occurs in the
mitochondria Produces more ATP (34) 2. Anaerobic respiration- does
NOT require oxygen -Occurs in the cytoplasm -Produces less ATP (2)
Slide 4 Three Stages of Cellular Respiration 1.Glycolysis (takes
place in the cytoplasm) 2. Krebs Cycle (takes place in the
mitochondria) 3. Electron Transport Chain (takes place in the
mitochondria) Slide 5 Cellular Respiration Slide 6 Glycolysis 1 st
stage Takes place in the cytoplasm Has a total of 2 ATP (Produces 4
ATP but uses 2 ATP) Anaerobic respiration (no oxygen) Slide 7 Krebs
Cycle (AKA: Citric Acid Cycle) 2 nd stage Takes place in
mitochondria Produces 2 ATP Aerobic Respiration (requires oxygen)
Slide 8 Electron Transport Chain 3 rd stage Takes place in the
mitochondria Produces 32 ATP Aerobic Respiration (requires oxygen)
Slide 9 Cellular Respiration Glucose + Oxygen Glycolysis 2 ATP
Krebs Cycle 2 ATP Electron Transport Chain 32 ATP Carbon dioxide +
Water + 36 ATP = Occurs in cytoplasm Occurs in mitochondria
anaerobic aerobic Slide 10 Anaerobic Respiration Fermentation:
releases ENERGY from FOOD by producing ATP in the ABSENCE of OXYGEN
Breaks down GLUCOSE (SUGAR) Does NOT require oxygen 1. Alcoholic
fermentation Occurs in yeast cells Produces 2 ATP, carbon dioxide
and alcohol Carbon dioxide causes bread to rise 2. Lactic Acid
fermentation Occurs in muscle cells Produces 2 ATP, carbon dioxide
and lactic acid Lactic acid causes muscle soreness Slide 11 1.

organisms) Slide 16 1.What is the purpose of photosynthesis? What
is the purpose of cellular respiration? 2.Where does photosynthesis
occur? Cellular respiration? 3.Describe what would happen if the
amount of sunlight available to a plant became limited. How would
that affect cellular respiration? 4.What are the reactants in each
of these equations? What are the products?
