Which of the following situations or phrases most accurately describes the citric acid cycle?
Bond [772]

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.

Energy enters a food chain as heat energy and leaves it as light energy.
hjlf

Answer:

The statement that says "Energy enters a food chain as heat energy and leaves it as light energy" is false.

Explanation:

The energy that enters the food chains, first of all, is light energy from the sun. This energy is assimilated by plants to convert it into chemical energy, through  photosynthesis.

When energy flows from producers, plants, to consumers and decomposers, a great amount of <u>energy is lost, in the form of </u><u>heat energy</u>, due to the metabolism of living beings. Additionally, the second law of thermodynamics states that when energy passes from one form to another it leads to disorder in the system, which would also explain the loss of energy.

The true statement is "Energy enters a food chain as <u>light energy</u> and leaves it as <u>heath energy"</u>.
