Diffustion

 How different molecule in and out of cell 

cytosol -

O2  can go straight to the cell 

can diffuse into cell from high concentration to low centration 

molecule that are charge that are positive or negative 

example sodium ion ( if the molecule is big ) cannot passthrough the membrane 

so that we need specific channel 

facilitate by protein is call facilitate diffusion 

transport 

move molecule from low to high 

base on concentration gradient 

inside of the cell 

high concentration 

opposite direction of diffusion

protein you need the little extra to move molecule 

we need energy to transport molecule called ATP 

Glycolysis 

Transition step between glycolysis and Krebs 

each step 

what are the product 

ATP main energy of all cell 

aerobic respiratory eukaryotic cell enzyme catalyzed reaction 3 major step 

cytosol outside of mi 

Glycolysis break down 2 molecule 2 ATP are generated 

electrocarry

organic intermediates enter into the krebs cycle  take place in the matrix of mitochondria 

oxidation of organic intermediates complected in this cycle 

2 ATP are generate in this process as well as carbondioxide waste 

glycolysis and Kreb cycle 

has electron transport change 

inner mitochondian membrane 

pass along the series of chemical reaction 

proton are actively pump 

high concentration of proton 

proton pump election

O2 final ATc

if oxygen not present ATC shut down 

electron transfer stuff 

oxidized combine or become combined chemically with oxygen.

osmosis 

flow of proton moving charge 

energy is use to generate to releae ATP 

then ADP 

with estimated by scientist 

without oxygen
