Weight loss can occur when glucose is oxidized to CO2 rather than being stored as glycogen. The first step in glucose oxidation

is glycolysis. A 1930s diet drug, DNP, made the inner mitochondrial membrane permeable to protons, increasing the rate of glycolysis. What is the explanation for the DNP-induced increase in glycolysis
A. High ATP activates phosphofructokinase.
B. High AMP inhibits phosphofructokinase.
C. High ADP activates phosphofructokinase.
D. DNP also makes the inner mitochondrial membrane leaky to glucose, increasing the ability of the mitochondria to perform glycolysis.

Increasing permeability of the inner mitochondrion membrane to protons uncouples proton transport with ATP synthesis. As ATP synthesis in oxidative phosphorylation across ATP synthase is dependent on the proton gradient, increasing permeability of the membrane would reduce the amount of ATP synthesized as less protons will flow through ATP synthase. ADP is thus not converted to ATP and there is high amounts of ADP and AMP. High amounts of ADP and AMP will activate the glycolytic pathways and hence actively PFK hence the answer would be C.

How does the concentration of salt in water affect the rate of osmosis?
Nata [24]
The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.
Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.

dmitriy555 [2]

Answer:

The correct option is D. <u>The chemical bond breaks between the second and third phosphate groups.</u>

Explanation:

Adenosine phosphate (ATP) can be described as main energy-carrying molecules which are required by each cell to carry out its normal functions.

A molecule of ATP comprises of the nitrogenous base Adenine, pentose sugar ribose and three molecules of phosphate.

The bond between the second and third molecule carries high amounts of energy. When this bond is broken, huge amounts of energy is released which is used by the cells to carry out essential processes.
