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
