|
How many different ways are ATP made in bacteria?
|
2 ways; substrate level phosphorylation of ADP and chemiosmotic ATP production
|
|
How does substrate level phosphorylation occur?
|
It is the direct transfer of a high energy phosphate from some compound to ADP
|
|
How does a cell obtain the majority of its required ATP?
|
Chemiosmotic ATP production, that occurs during both respiration and photosynthesis
|
|
How does Chemiosmotic ATP production occur?
|
1.Energy is stored in a Electrochemical Gradient 2.the stored energy is used to drive phosphorylation of ADP
|
|
How do chemotrophs create an H+ gradient?
|
Energy from a high energy electrons produced by oxidation of chemical compounds
|
|
How do phototrophs create an H+ gradient?
|
Photosynthetic energy captured from the light reactions of photosynthesis
|
|
How is the proton gradient produced in mitochondria?
|
H+ are pumped across the inner membrane into the intermembrane space. They diffuse through outer mem.(porins)
|
|
How is the proton gradient produced in chloroplasts?
|
Chloroplasts have internal thylakoids. Protons are pumped across the thylakoid membranes into the thylakoid space
|
|
Graphically show how Chemiosmotic generation of ATP works in mitochondria and chloroplasts?
|
Mitochondria send H+ to outside while chloroplasts send to inside vescicles.VIEW IMAGE(WITH PH)
|
|
Where are the ATP Synthase units located in the mitochondria?
|
The Inner Membrane(cristae)
|
|
Where are the ATP Synthase units located in the chloroplast?
|
The thylakoid membrane
|
|
In what ways are the ATP synthase units reversible?
|
 If proton gradient exists then ADP will be phosphorlated. If not ATP will be hydrolyzed to pump H+ in intermem. space |
|
Where does the E to transport H+ across inner membrane come from?
|
Oxidation of carbon compounds. Carbon compounds are the electron donor, and oxygen is the terminal electron acceptor
|
|
Photosynthesis occurs in chloroplasts and the light energy captured helps with what two things?
|
Production of Proton gradient and produce NADPH, the reducing agent used in the reduction of carbon
|
|
What is the purpose of the ETC in Chemiosmotic ATP production?
|
The Electron Transport chain produces the initial proton gradient
|
