Chaperter 6&7 Questions

Question 0

What is the job , structure, and why do we call it selectively permeable ?

Answer 0

Job: maintains homeostasis
Structure: membrane
Selectively permeable : picks and chooses what goes in and out

Question 1

Name and explain three things that affect diffusion

Answer 1

Concentration - the higher the concentration that faster the diffusion

Temperature- the higher the temperature that faster the diffusion

Pressure - the greater the pressure the faster the diffusion

Question 2

Name the three types of solution and explain what they are ?

Answer 2

Isotonic - concentrations are equal on both sides of membrane of movement occurs no overall charge 50% h2o in and out

Hypotonic - concentration of dissolved substances is lower than the concentration inside the cell
15% sugar 85% h20 outside
85% sugar inside 15% h2o

Hypertonic - concentration of dissolved substances is higher than the concentration out side the cell
Outside. 10% h2o 90% sugar
In 90% h2o 10%sugar

Question 3

Normal diffusion thorough the plasma membrane the cell use of no energy

Answer 3

Passive transport

Question 4

Movement of molecules from an area of high concentration

Answer 4

Active transport

Question 5

No energy expanded on the past of the cell materials flow through channels made by the transport proteins

Answer 5

Facilitated diffusion

Question 6

Is the study of the flow and transformation of energy in the universe

Answer 6

Thermodynamics

Question 7

What is law 1

Answer 7

The conservation of energy

Energy can be converted from one to another but can’t create or destroy

Question 8

What is law 2

Answer 8

Energy can not be converted

Question 9

What is ATP and how is it used

Answer 9

Cells needed to survive

1) energy is used for biological food
2) releasing food energy
3) as an energy currency

Question 10

How do animals create food energy ?

Answer 10

All food is broken down smaller and smaller bits from stomach to intestine to blood stream to cells

Question 11

Answer 12

Co2+ 6h2o+light +c6h12o6+ 6o2

Carbon dioxide 6 water sunlight sugar 6 oxygen

Question 13

What happens in the process of photosynthesis

Answer 13

Light energy is converted to chemical energy then stored

Question 14

What is a green pigment that has the ability to trap solar energy

Answer 14

Chlorophyll

Question 15

How do we see color

Answer 15

The color you see is reflected by the sun in different wave lengths

Question 16

What are two types of reactions in photosynthesis

Answer 16

Light reaction

Calvin reaction

Question 17

What does light energy and Calvin cycle do ?

Answer 17

Light energy- energy converted into chemical (photo part)

Calvin cycle - (dark reaction synthesis part) sugars using carbon dioxide

Question 18

Answer 18

Chemosynthesis

Deep sea organisms &marsh organisms

Question 19

Process food molecules broken down

Answer 19

Respiration

Question 20

What are two types of respiration and how are they used

Answer 20
