In this case, the unpleasant behavior is the headache, and taking aspirin is a behavior of Nancy, which cut of the stimuli, that is pain relieving. In negative reinforcement a particular behavior is increased, in order to remove the unpleasant stimulus.
Oxidative Phosphorylation: Chemiosmosis and the Electron Transport Chain
Because, it is the process by which they make or produce their food with the help of sunlight, water and carbon dioxide.
If photsynthesis is not there then there would be no production of food and ultimatley plants will die.
Valinomycin is an Ionophores- i.e it makes the inner membrane permeable to compounds which are ordinarily unable to cross.
The amphipathic molecules dissolve in phospholipid bilayers of the mitochondria
It shields the electric charge as the ion passes through the membrane, providing a polar environment for the ion and a hydrophobic face to the other side. mobile carrier catalyzes the electrical movement of K+ across phospholipid bilayers. Hence Accumulation of potassium inside the mitochondria
This dissipates the essential transmembrane electrochemical gradients causing tremendous metabolic upheaval in the mitochondria.
