Roman55 [17]
3A- Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

3B- Negative feedback loops are used to maintain homeostasis and achieve the set point within a system. Negative feedback loops are characterized by their ability to either increase or decrease a stimulus, inhibiting the ability of the stimulus to continue as it did prior to sensing of the receptor.

Hope I’ve helped ;)

Electron transport refers to the transfer of of electrons from electron donors to electron acceptors via a reduction-oxidation reaction.  

In the mitochondria the process is called Oxidative phosphorylation whereas in the Chloroplast it is called Photo-phosphorylation since it utilizes light.

Chemiosmotic mechanisms allow the movement of ions across a semi-permeable membrane down their electrochemical gradient.

In both mitochondria and chloroplast,have these mechanisms for the production of ATP .
