What is the name of an organism that makes its own food.
Autotroph
100
How much ATP is created from cellular respiration?
36-38
100
What are the two different types of cellular respiration?
Hint: One uses oxygen, one does not.
Aerobic Respiration
Anaerobic Respiration
100
What is the ultimate energy source for most ecosystems?
The sun
100
What is the substance created during exercise which is responsible for the "burning"/sore feeling in your muscles?
Lactic Acid
200
Where does the light dependent reactions and calvin cycle occur?
light-dependent: thylakoids
calvin cycle: stroma
200
Define cellular respiration.
A process that changes glucose (sugar) into ATP (energy) the cell can use to perform its functions.
200
Name 1 way humans use fermentation to their advantage.
We make food using fermentation. Bread, cheese, alcohol, yogurt, etc.
200
How much energy does a consumer get from its prey? (What percentage of all of that animal's energy makes its way to the consumer?)
10%
200
What does products and reactants mean?
products- what is made in a chemical reaction (what you end with)
reactants - what goes into a chemical reaction (what you start with)
300
During photosynthesis, different gasses move in and out of plant cells. What moves in and what moves out?
Carbon dioxide moves in and oxygen moves out
300
Where does each step of cellular respiration occur?
1. Glycolysis
2. Krebs Cycle
3. Electron Transport Chain
1. Glycolysis - cytoplasm
2. Krebs Cycle - Matrix of mitochondria
3. Electron Transport Chain - The membrane of the mitochondria
300
What type of fermentation do animals/people do?
Lactic Acid Fermentation
300
A tree has 23,500 calories of energy. A giraffe comes up to eat the plant. A lion then eats the giraffe. How many calories of energy does the lion consume?
235 calories
300
Explain what would happen if the primary consumer of an ecosystem went extinct
Their prey would overpopulate and out-compete one another for food until there was no more of their food - throwing the entire ecosystem into a spiral.
400
What is light absorbed by and where does it happen?
Chlorophyll absorbs the light and it happens in the thylakoids of the chloroplast.
400
What is the equation for Cellular Respiration?
C6H12O6 + 6O2 -> 6CO2 + 6H2O
400
What type of fermentation happens with yeast?
Alcoholic Fermentation
400
What level on a trophic pyramid would the mouse be?
Primary Consumer
400
What are the byproducts of cellular respiration and photosynthesis?
cellular respiration - carbon dioxide
photosynthesis - oxygen
500
What is the equation for photosynthesis?
6CO2 + 6H2O -> C6H12O6 + 6O2
500
What are the 3 steps of cellular respiration? What happens at each step?
1. Glycolysis (makes 2 ATP)
- glucose broken down into pyruvate
2. Krebs Cycle (makes 2 ATP)
-break down pyruvate further to get electrons (NADH & FADH2), release CO2, get 2 ATP
3. Electron Transport Chain (makes 32-34 ATP)
- Electrons move through the ETC . Protons move from high to low concentration through ATP synthase
500
How much ATP is created from fermentation?
2 ATP

Name the first 4 levels of a trophic pyramid, starting with plants and continuing in order from there.
producers - plants
primary consumers - herbivores
secondary consumers - omnivores or carnivores
tertiary consumers - top of the food chain
500
Where does photosynthesis, cellular respiration, and glycolysis primarily occur?
photosynthesis - chloroplast
cellular respiration - mitochondria
fermentation - cytoplasm
