Which of the following situations or phrases most accurately describes the citric acid cycle?
a) a chaotic, unregulated traffic circle
b) "all roads lead to rome"
c) the shortest distance between two points is a straight line
d the main center of energy production in aerobic respiration

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.

because the light is a great source of energy for the plants to survive. (i hope this )
