(1 point)
stored chemical energy is broken down and released in the cytoplasm.
Stored chemical energy is broken down and released in the mitochondria.
Stored chemical energy can be used immediately and is released in the cytoplasm.
Stored chemical energy can be used immediately and is released in the mitochondria.
Stored chemical energy is broken down and released in the mitochondria.
for the students in conexus or something i forgot this is the answer to question 3
Stored chemical energy is broken down and released in the mitochondria.
The best statement that describes energy release in cellular respiration is: "Stored chemical energy is broken down and released in the mitochondria."
To understand why this statement is correct, we need to understand the process of cellular respiration. Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and ATP (adenosine triphosphate), which is the energy currency of the cell.
Cellular respiration takes place in multiple steps, including glycolysis, the Krebs cycle, and oxidative phosphorylation. While some of these steps occur in the cytoplasm, the majority of energy release occurs in the mitochondria.
During glycolysis, glucose is broken down into pyruvate molecules in the cytoplasm, but only a small amount of ATP is produced at this stage. The remaining steps of cellular respiration, including the Krebs cycle and oxidative phosphorylation, take place in the mitochondria. In these steps, the pyruvate molecules are further broken down, and the majority of ATP production occurs.
Therefore, it is in the mitochondria where stored chemical energy in the form of glucose is broken down and released, leading to the production of ATP.
