CHP 6 Flashcards
Waste Products of Cellular Respiration
CO2-Carbon Dioxide
H2O-Water
Ultimate source of energy in food
Sun
Consumer
eat plants and other animals
Producer
depended upon for food
Photosynthetic organisms
Autotrophs
Self-Feeders, producers, produce own energy through photosynthesis
Heterotrophs
Other-feeders, consumers, must consume other plants/animal for energy
Breathing
exchanges oxygen gas and carbon dioxide gas with blood and outside air
Cellular Respiration
produces ATP and exchanges oxygen gas and carbon dioxide gas between surroundings
Equation of Cellular Respiration
Glucose + Oxygen > Carbon Dioxide + Water+ Energy
Redox Reactions
Electrons are lost (oxidation) from one substance and added/gain (reduction) to another substance
cellular respiration: glucose oxidized
Oxygen reduced
3 Electron acceptors & where they can be found
1st= NAD+ found at top
2nd=?
Final= Oxygen at bottom
What reactions take place during glycolysis?
C6 glucose molecule is split in half to form pyruvic acid
donate high energy electrons to NAD+=NADH
Product(s) of Glycolysis
Pyruvic Acid
Where in the cell does glycolysis, citric acid, and electron transport chain occur?
G: Cytosol
CA: Mitochondria
ET: Mitochondria
of ATP’s produce during glycolysis, citric acid and electron transport chain from one molecule of glucose
G:2 molecules of ATP
CA: 2 molecules of ATP
ET: 32-34 molecules of ATP
Total 36-38 molecules of ATP
