Interactions

Question 1

Enzymes

Answer 1

Proteins
Enzymes have an active site where substrates bond


Question 2

Naming enzymes

Answer 2

Most enzymes end in “ase”
Enzymes are very specific to a Substrate
Lactase -> Lactose
Nuclease-> Nucleotides
“brakes down

Question 3

Models of enzymes action

Answer 3

1. lock and Key:
   enzyme + substrate fit perfectly
2. Induced Fit Model:
   - enzyme “slightly”
   Changes shape to better hug the substrate

Question 4

Enzyme reaction

Answer 4

Anabolic:
- build molecuies
- photosythesis endothermic
catabolic:
- breau down
- Ceir resperation
- exothermic

Question 5

Types of inhibitors

Answer 5

Competitive
-both compete for active site
Non competitive
-inhibitor binds to allosteric site and changes the shape of the active site

Question 6

Prokaryotic cells

Answer 6

Bacterial cells
Do not contain membrane-bound organelles
Do not contain a nucleus

Question 7

Prokaryotic cells and eukaryotic cells similarities

Answer 7

Surrounded by a cell membrane
Contain DNA
Alive
Contain ribosomes

Question 8

Eukaryotic cells

Answer 8

Contain membrane bound, organelles
Animal cells
Plant cells
Larger and more complex
Contain a nucleus

Question 9

Water potential

Answer 9

The tendency of water to move from one place to another

H2O flows from a high water potential to a low water potential

H2O flows from more water to less water. 

Question 10

Carrying capacity

Answer 10

The amount of individuals in an ecosystem

Question 11

Exponential growth

Answer 11

Rapid growth
Unlimited resources
Few predators
Typically seen in bugs, frogs or recovering populations

Question 12

Logistic growth

Answer 12

Limited growth
Controlled by limiting factors
Regulated by carrying capacity

Question 13

Density dependent

Answer 13

Can be biotic-living, or abiotic-nonliving
Food, water, habitat, number of predators, disease, competition

Question 14

Density independent

Answer 14

Can be biotic or abiotic, mostly abiotic, natural disaster, weather
