What is respiratory chain?
In respiratory chain (also called electron transport system) electrons are transported in a series of oxidation-reduction steps to react, ultimately with molecular oxygen.
Which oxidation reduction substances take part in respiratory chain.
The oxidation reduction substances which take part in respiratory chain are:
- a coenzyme called coenzyme Q
- a series of cytochrome enzymes
- molecular oxygen (O2)
Define oxidative phosphorylation.
Synthesis of ATP in the presence of oxygen is called oxidative phosphorylation.
Define Chemiosmosis Or what is chemiosmosis.
Chemiosmosis is the process that used membranes to couple redox reactions to ATP production. Electron transport chain pumps protons across the membrane of thylakoids in case of photosynthesis into the thylakoids space. The energy use for this pumping comes from the electron, moving through to electron transport chain.
What are the products of light reaction.
NADPH2, and ATP
Name the process which acts as energy capturing and energy releasing.
The photosynthesis acts as an energy capturing while respiration as an energy releasing process.
