Unit 3 Flashcards
Cellular Respiration Formula
C6H12O6 + 6O2 → 6CO2 + 6H2O + ENERGY
Glucose + Oxygen = Carbon Dioxide + Water + ATP
Where does glycolysis take place
in cytoplasm, and it creates some ATP
Mitochondria structure
- two membranes (outer and inner)
- inner membrane is folded up
- innermost portion called the matrix
Krebs Cycle (citric acid cycle) function
- creates some usable ATP
- where CO2 product is made
- takes place in mitochondria matrix
Electronic Transport Chain function
- majority of ATP made
- where O2 is used and H2O is made
- takes place on inner membrane of mitochondira
What are two ways carbon often enters the atmosphere?
Combustion and Respiration
What organisms carry out respiration?
plants and other photosynthetic organisms
What organisms carry out the job of breaking down dead components?
Decomposing fungi, bacteria, and worms
What would happen if decomposition didn’t occur?
Carbon would be trapped inside dead organisms, leaving less carbon dioxide for photosynthesis, and resulting in a pile up of dead organisms
What are four materials that contain stored carbon?
coal, oil, peat, and natural gas (fossil fuels)
How do humans use materials of carbon sink?
We burn them for energy sources
How do carbon sink materials enter the air?
Combustion
What processes involve combustion?
- driving a car
- flying a plane
- riding on a train
- using a gas stove
- riding the bus to school
- using an outdoor grill
What are the two steps of photosynthesis?
- Light Dependent Reaction
- Light Independent Reaction (Calvin cycle)
What is a Light Dependent Reaction
- Occurs in the thylakoid of the chloroplast.
- Chlorophyll is the light acceptor.
- Water is split to make O2
