Term
| Where does the excess H+ build up vs excess OH-? |
|
Definition
H+ builds up on the cytosol P side
OH on N side= in Matrix |
|
|
Term
|
Definition
enerrgy releaed when H+ move across the inner mito membrane from the outside and into the matrix
measured in volts or calories per mole |
|
|
Term
| Complex 1 has =H+ in - = # ATP |
|
Definition
| 4H+ in intermembrane space= 1ATP |
|
|
Term
| Complex3 has =H+ in - = # ATP |
|
Definition
| 4H+ in the intermembrane space with in combination of complex 4= 1.5 ATP total |
|
|
Term
| Complex 4 has =H+ in - = # ATP |
|
Definition
| 2H+ in the intermembrane space with in combination of complex 4= 1.5 ATP total |
|
|
Term
| H+ can re enter the matrix thru |
|
Definition
| Fo channel. PMF is catalyzed by F1 complex associated with Fo |
|
|
Term
|
Definition
| ADP +Pi +{H+}out <_> ATP +H2O + {H+}in matrix |
|
|
Term
| What change confirmation of F1 |
|
Definition
| beta subunit of F1 change confimation as gamma associates with each turn. F1 is matrix side Fo innermembrane side |
|
|
Term
| What has the binding site for ATP |
|
Definition
| Beta, gamma associate with one f the 3 alpha/beta pairs forcing the other two nto different confirmation with different nt sites. |
|
|
Term
|
Definition
1. beta-ADP has ADP in site
2. the next has ATP in the site bound tightly
3. The 3rd site is empty w/no bound. |
|
|
Term
|
Definition
| gamme is counterclockwise as viewed from matrix side. |
|
|
Term
| What causes ATP to dissociate? |
|
Definition
| Confirmation change. B-ADP will then go to B-ATP |
|
|
Term
| ATP wont be released until? |
|
Definition
| ADP-Pi are loosely bound in another site. |
|
|
Term
| What causes the electrical and chemical gradient? |
|
Definition
| As e- flow in ETC they tak H+ with them across the membrane. |
|
|
Term
| For one turn of F1 there are --H+ flowing thru Fo = +H+ per ATP |
|
Definition
10 H+ per turn
3.3H+ per ATP |
|
|
Term
|
Definition
| number of ATP molecules produces via oxidative phosphorylation per 2e- passing thru ETC |
