Cellular Respiration | MCQs

Explanation

One mole of glucose (180g) produces a maximum of 2827 kJ (kilojoules) of energy through cellular respiration.

This energy is released as ATP (adenosine triphosphate) and is used to power various cellular activities.

Explanation

• Glycolysis, the splitting of glucose, releases a small amount of energy that is enough to generate 2 ATP (adenosine triphosphate) molecules.
• This process occurs in the cytosol of cells and is the first step in cellular respiration.

Explanation

Each mole of ATP (Adenosine Triphosphate) stores energy equivalent to:

• 7.3 kilocalories (kcal) per mole (approximately)
• 17.3 kilojoules (kJ) per mole (approximately)

Explanation

In cellular respiration, each mole of glucose typically produces about 36-38 ATP molecules.

To determine how many moles of glucose are consumed to produce 180 ATP molecules, we can use the following calculation:

180 ATP/36 ATP or mole of glucose = 5 moles of glucose

Thus, 5 moles of glucose are consumed to produce 180 ATP molecules.

Explanation

• The electron transport chain (ETC) is the stage of aerobic respiration that takes place at the cristae of mitochondria.
• The cristae are specialized infoldings of the mitochondrial inner membrane, where the ETC complexes are embedded.
