about ATP synthase
[Cellular Respiration] Which of the following interactions provides the mechanical energy needed to promote ATP production?
Non-polar interaction
Salt bridge formation
Polar interaction : Attractive
Polar interaction : Repulsive
Fill in the blank: Addition of electron(s) to a substance is the process of (1). Removal of electron(s) from a substance is the process of (2). In terms of moving the electrons from one substance to another, electron carriers that are (3) or are (4) can be employed. Bacteria can have electrons move along the (5) membrane. (6) move each electron to stronger and stronger electron acceptors in the membrane. Ultimately, the electron will be added to (7) to generate water. Meanwhile, the protons generated during all this electron transfer are transported back across the membrane to form (8).
The production of a hydrogen ion concentration gradient powers the production of ATP in both photosynthesis and cellular respiration. 2,4-Dinitrophenol (DNP) is an organic compound that 'undoes' the hydrogen ion concentration gradient without the production of ATP. It does this by increasing the membrane permeability to hydrogen ions. One use of DNP is as a herbicide.For a brief period in the 1930s, DNP was marketed as a diet pill. Because DNP prevents the production of ATP, the human body will begin to use alternate forms of energy. The result is an increase in the metabolism of fats in the body, thus reducing total body fat. In the presence of DNP, the energy that normally would be converted to ATP for use in the cells is converted to heat instead, causing dangerously high body temperatures.DNP is classified as an illegal substance in Canada and the U.S. although it is still marketed as a commercial chemical. In recent years, several deaths have been reported, primarily in the…
