which statement best describes energy release in cellular respiration
Answers:
Stored chemical energy is broken down and released in the cytoplasm
Stored chemical energy is released in the mitochondria
Stored chemical energy is broken down and released into the mitochondria
Stored chemical energy is released in the cytoplasm
Stored chemical energy is released in the mitochondria
The correct statement that best describes energy release in cellular respiration is:
Stored chemical energy is broken down and released in the mitochondria.
The correct answer is: Stored chemical energy is released in the mitochondria.
To determine the correct answer, we need to understand the process of cellular respiration. Cellular respiration is the process by which cells convert glucose (a sugar) into usable energy in the form of ATP (adenosine triphosphate). This process takes place in the mitochondria, which are commonly referred to as the "powerhouses" of the cell.
During cellular respiration, stored chemical energy in glucose is broken down through a series of biochemical reactions. These reactions occur in multiple stages, such as glycolysis (which takes place in the cytoplasm) and the Krebs cycle and electron transport chain (which occur in the mitochondria).
However, the majority of the energy released during cellular respiration occurs in the mitochondria. This is because the final stages of cellular respiration, specifically the Krebs cycle and electron transport chain, take place in the mitochondria.
Therefore, the statement "Stored chemical energy is released in the mitochondria" is the most accurate description of energy release in cellular respiration.
