3 parts of cell theroy

1. a cell is the smallest unit of life
2. all living thing are made up of cells
3. all cells arise from previous cells

1

3 types of cells are?

1. Archae
2. Prokaryotes
3. Eukaryotes

2

How long ago did cells originate?
How long ago before we see the cells today?

3.5 billion years ago the 1st cell was discovored
2 million years ago we see the same cells as we see today

3

Halophies

extreme salt conditions

4

psycrophiles

extreme cold

5

acidophiles

low ph

6

Barophiles

extreme pressure

7

xerophiles

grow in very little water

8

Alkaphiles

high ph

9

Anaerobes

little o2

10

Facultative anerobes

w or w/o o2

11

Endolithes

rocky minerals

12

Thermophiles

high temps

13

What is apoptosis?

cell death, self defense mechanism

14

Where is the ATP produced?

Mitochondria

15

What is the equation for cellular respiration?

C6 H12 O6+O2->Energy+CO2+H2O

16

What is the equation for photosynthesis?

CO2+Energy+H2O->C6 H12 O6+O2

17

How many ATP total?

36

18

What are the steps of cellular respiration?

1. Glycosis
2. Krebs Cycle
3. ETC

19

Where does glycosis take place?

Cytoplasm

20

Where does the krebs cycle take place?

mitochondia

21

where does ect take place?

mitochondria

22

How many ATP does Glycosis yeild?

2 ATP

23

How many ATP does Krebs Cycle yeild?

2 ATP

24

How many ATP does ETC produce?

32 ATP

25

Steps of Apoptosis

1. Stimulus of cell internal/external
2. organelle membranes begin to break down dna is exposed mitochondria leak out & stop energy production ER releases its calcium
3. Activation of cytoplasmic enzymes destroy macromolecules riot within the cell enzymes attack one another
4. cell itself will tear itself into chunks flopsasis enzyme will break up the cell

26

What is the 1st step of apoptosis?

Stimulus. Internal/External - Initiation

27

What is the 2nd step in apoptosis?

organelle membranes begin to breakdown, dna is exposed. mitochondria leak out & enhance apoptosis. stops energy production er releases its calcuim

28

3rd step of apoptosis?

activation of cytoplasmic enzymes
-distroy macromolecules
riot within the cell
enzymes attack eachother

29

What is the 4th step of apoptosis?

cell itself will tear itself into chunks flopsasis enzyme that breaks up the cell
