Monday 12/8/14
• Agenda-respiration
• Finish photosynthesis handout, page 122, & job qualifications paragraph
• These were assigned Thursday & Friday (due tomorrow)
• Respiration
• Fermentation
• Word-define-picture-use in a sentence
• Show me when you are done
• 8 points
respiration
• What is the first stage of respiration?
• Takes place in the cytoplasm
• Glucose is broken down into smaller molecules
• A small amount of energy is released
respiration
• What is the second stage of respiration?
• Takes place in the mitochondria
• Smaller glucose molecules are broken down into smaller ones
• Needs oxygen
• Releases a lot of energy
respiration
• Besides energy, what are the 2 other products of respiration?
• Carbon dioxide
• Water
• These are released when you exhale (breathe out)
Respiration equation
How are photosynthesis & respiration related
Tuesday 12/9/14
• Agenda-fermentation
• Warm up
• Finish missing work (see board)
fermentation
• What is fermentation?
• It is a way for cells to get energy from food without using oxygen.
• Energy released is less than during respiration.
fermentation
• What is alcoholic fermentation?
• Occurs in yeasts and other single celled organisms
• Products are alcohol, carbon dioxide and energy
• Used in baking bread & making beer.

Wednesday 12/10/14
• Agenda fermentation
• Warm-up
• What is the difference between respiration and fermentation?
fermentation
• What is lactic acid fermentation?
• Occurs in muscles when they don’t have enough oxygen
• Occurs during physical activity
• Lactic acid is a product that makes your muscles sore
Lactic acid fermentation
• ATP is
Energy
ATP is released energy
Lactate is lactic acid
Lactic acid fermentation
Start/end
