The correct answer is: B) "All roads lead to Rome"
Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle that connects carbohydrate, fat, and protein metabolism so “all the roads” from the different metabolic pathways come to this cycle.
Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.
Cerebrospinal Fluid
Produced by the choroid plexuses of the brain, the cerebral spinal fluid is contained in the subarachnoid cavity and spinal canal. It is reabsorbed by the arachnoid granulations.
Besides acting as a cushion for the CNS, the cerebral spinal fluid plays a critical part in the immunology of the central nervous system, blood flow in the CNS and autoregulation.
