Getting protein where it needs to go

Question 12

What are vesicles?

Answer 12

Little containers

Question 13

Lysosomes..

Answer 13

Engulf bad materials and break it down

Packing receiving

Question 14

Peroxisomes…

Answer 14

Detoxer!

Have materials to take toxins and bring it down to water

Question 15

What do peroxidases do?

Answer 15

Take free radical and changes to hydrogen peroxide

Question 16

What do catalases do?

Answer 16

Take hydrogen peroxide and change to water so our body can use it

Question 17

What influences a reaction?

Answer 17

Temperature and environment

Question 18

How does temperature effect velocity?

Answer 18

When temp increased, velocity is increased. Velocity provides the energy for reaction

Question 19

What happens when you increase concentration?

Answer 19

Increases availability

Question 20

What is activation energy?

Answer 20

Energy requires for reaction to happen

Ex. Kitchen match (just to get it going)

Question 21

What is an exothermic reaction?

Answer 21

Give off energy (phosphate breaks off ATP to become ADP to become energy)

Question 22

What is an endothermic reaction?

Answer 22

Ending product has more energy than original reaction

Ex. Seed turning to apple/tree

Question 23

Characteristics of enzymes:

Answer 23

Lower activation energy and speed up rate of reaction

Question 24

Catalyst

Answer 24

Helps chemically speed up rate of reaction

Question 25

Properties of water:

Answer 25

• Very polar (pulls on positive and negative)
• Universal solvent- Breaks down most things that are hydrophilic
• Ionic bonding substance loves water
• Solute- One that it dissolves (salt)
• Blanketing- Negative side of water surrounds pos. solute
• Hydrophobic- Usually electrically neutral, usually very non polar
• High heat adversion
• Adhesive- Sticky to itself
• Solinity will lower heat of vaporization
• Water gets bigger when frozen
• Lubricant- lines everything in body

Question 26

Salt…

Answer 26

Ironically bonded substance
Inorganic
Conducts electricity

Question 27

Osmotic fluid

Answer 27

Blood and water will mix

Question 28

Characteristics of Acids

Answer 28

Ironically bonded
When added to water, freely release hydrogen ion
Proton donor
Ionize in water
H+

Question 29

Characteristics of bases

Answer 29

Receive proton
Proton receptor
OH- 
High concentration
Alkaline compounds ironically bonded, ionize in water
