Answer:
Gluconeogenesis is blocked due to pyruvate dehydrogenase complex inhibition, which starves neurological tissue of glucose.
Explanation:
Metabolism is involved directly or indirectly in all processes conducted in living cells. The brain, popularly viewed as a neuronal–glial complex, gets most of its energy from the oxygen-dependent metabolism of glucose, and the mitochondrial pyruvate dehydrogenase complex (PDC) plays a key regulatory role during the oxidation of glucose. Pyruvate dehydrogenase kinase (also called PDC kinase or PDK) is a kinase that regulates glucose metabolism by switching off PDC. Four isoforms of PDKs with tissue specific activities have been identified. The metabolisms of neurons and glial cells, especially, those of astroglial cells, are interrelated, and these cells function in an integrated fashion. The energetic coupling between neuronal and astroglial cells is essential to meet the energy requirements of the brain in an efficient way. Accumulating evidence suggests that alterations in the PDKs and/or neuron-astroglia metabolic interactions are associated with the development of several neurological disorders. Here, the authors review the results of recent research efforts that have shed light on the functions of PDKs in the nervous system, particularly on neuron-glia metabolic interactions and neuro-metabolic disorders.
<span>Cortisol opposes the action. Cortisol is a hormone found in the adrenal gland. The hormone helps break down protein and fat in the body. Cortisol may be released when you are under high stress and it increases the amount of time it takes for a injury or wound to heal..</span>

Answer:
The correct answer is D. On the plasma membrane.
Explanation:
Prokaryotes do not have mitochondria to synthesize ATP but ATP synthesis takes place in prokaryotes on the plasma membrane as the plasma membrane contains the enzymes that are required for ATP synthesis.
The process of ATP synthesis is just like in the mitochondria. NADH helps in building the proton gradient in the outer portion of the membrane by the help of electron carriers embedded in the plasma membrane. Then these protons come back in the cytoplasm through ATP synthase enzyme complex.
This entry of protons helps in the generation of ATP from ADP and inorganic phosphate with the help of ATP synthase enzyme. Therefore the correct answer is D. On the plasma membrane.
