Photosynthesis

100

What is the name of an organism that makes its own food. 

Autotroph

200

Where does the light dependent reactions and calvin cycle occur?

light-dependent: thylakoids

calvin cycle: stroma

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

400

What is light absorbed by and where does it happen?

Chlorophyll absorbs the light and it happens in the thylakoids of the chloroplast.

500

What is the equation for photosynthesis?

6CO₂ + 6H₂O -> C₆H₁₂O₆ + 6O₂

Cellular Respiration

100

How much ATP is created from cellular respiration?

36-38

200

Define cellular respiration.

A process that changes glucose (sugar) into ATP (energy) the cell can use to perform its functions.

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

400

What is the equation for Cellular Respiration?

C₆H₁₂O₆ + 6O₂ -> 6CO₂ + 6H₂O

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 

Fermentation

100

What are the two different types of cellular respiration?

Hint: One uses oxygen, one does not.

Aerobic Respiration

Anaerobic Respiration

200

Name 1 way humans use fermentation to their advantage.

We make food using fermentation. Bread, cheese, alcohol, yogurt, etc. 

300

What type of fermentation do animals/people do? 

Lactic Acid Fermentation

400

What type of fermentation happens with yeast?

Alcoholic Fermentation

500

How much ATP is created from fermentation?

2 ATP

Energy Flow

100

What is the ultimate energy source for most ecosystems?

The sun

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%

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

400

What level on a trophic pyramid would the mouse be?

Primary Consumer

500

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

Misc.

100

What is the substance created during exercise which is responsible for the "burning"/sore feeling in your muscles?

Lactic Acid

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

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 are the byproducts of cellular respiration and photosynthesis?

cellular respiration - carbon dioxide

photosynthesis - oxygen 

500

Where does photosynthesis, cellular respiration, and glycolysis primarily occur?

photosynthesis - chloroplast

cellular respiration - mitochondria

fermentation - cytoplasm
