Respiration
Unit 5
What are we doing?
• Essential Question:
– Could Cellular
Respiration take
place if plants were
not available?
• Objectives:
• Explain Cellular
Respiration
• Describe what
happens during
glycolysis
• Name two types of
fermentation
We Need Plants, We Need
Food
• Photosynthesis is directly related to Cellular
Respiration.
• Final products of photosynthesis is used for
cellular respiration.
• They form a cycle that stays fairly constant.
We Use Each Other…
• PHOTOSYNTHESIS EQUATION:
6CO2 + 6H2O + LIGHT ENERGY C6H12O6 + 6O2
• CELLULAR RESPIRATION EQUATION:
C6H12O6 + 6O2 6CO2 + 6H2O + ENERGY RELEASED
(ATP)
Organic
compounds
Glycolysis
Fermentation
(anaerobic)
ATP
Aerobic
respiration
ATP
Cellular Respiration
• The process that releases energy by
breaking down glucose and other
food molecules in the presence of
oxygen
• Three Main Stages
• Main goal to produce ATP
Stage 1
• GLYCOLYSIS-process in which one
molecule of glucose is broken in half
producing two molecules of Pyruvic
Acid
• 2 ATP go in (to get things going) 4
ATP are produced
• NADH is made from NAD+ (helps
energy get passed along)
• Happens in the Cytosol/Cytoplasm
Two Types of Cellular
Respiration
AEROBIC-PRESENCE
OF OXYGEN
(Also can be called
Respiration)
ANAEROBIC-ABSENCE
OF OXYGEN
(Also can be called
Fermentation)
Stage 2 (WITH OXYGEN)
• RESPIRATION
• Uses oxygen to release energy
• Happens in the Mitochondria.
• Pyruvic acid is passed and broken
down in the Kreb’s/Citric Acid Cycle
Stage 2 (Without Oxygen)
Anaerobic respiration/Fermentation.
• Lactic Acid
Fermentation
• Animals—produced
in your muscles
(sore)
• End product is
lactic acid and
NAD+
• Pickles, yogurt,
cheese
• Alcoholic
Fermentation
• Yeast and few other
microorganisms
• Makes is ethyl
alcohol and carbon
dioxide
• Bread
Electron Transport Chain
• Converts ADPATP
• Produces the most ATP (32 or 34)
• Occurs on cristae of mitochondria
• Electrons pass from one acceptor
giving off energy.
• Final electron acceptor is oxygen
making water.
Energy Tally
• 36 ATP for aerobic vs. 2 ATP for
anaerobic
– Glycolysis
– Kreb’s
– Electron Transport
2 ATP
2 ATP
32 ATP
36 ATP
• Anaerobic organisms can’t be too
energetic but are important for global
recycling of carbon
