A student made the following diagram to represent cellular respiration.
The title of the diagram is Cellular Respiration. An oval labeled Cell has five arrows around it. The arrow labeled Oxygen points towards the cell. The other four arrows labeled Glucose, Carbon dioxide, Water, and Energy point away from the cell.
Why is this diagram incorrect? (5 points)
Water is not formed during this process.
Carbon dioxide is not formed during this process.
The arrow for oxygen should point in the opposite direction.
The arrow for glucose should point in the opposite direction.
Please help me! I don't understand what the answer is!! PLEASE HELP!!!!!
The arrow for glucose should point in the opposite direction.
Oh, dear! It looks like this diagram has some errors. Don't worry, I'm here to help you. The correct answer is "Water is not formed during this process." In cellular respiration, glucose is broken down into carbon dioxide and water, releasing energy. So, water is indeed formed during this process.
Based on the given information, the diagram representing cellular respiration is incorrect for two reasons:
1. Water is formed during cellular respiration: One of the arrows in the diagram points away from the cell and is labeled "Water." This is incorrect because water is indeed formed as a byproduct of cellular respiration.
2. The arrow for glucose should point in the opposite direction: Another error in the diagram is that the arrow labeled "Glucose" points away from the cell. However, glucose is the initial reactant that enters the cell during cellular respiration, so the arrow for glucose should point towards the cell.
Therefore, the correct answer is:
Water is not formed during this process.
The arrow for glucose should point in the opposite direction.
Based on the given information, the correct answer to the question "Why is this diagram incorrect?" is:
The arrow for glucose should point in the opposite direction.
To understand why the diagram is incorrect, we can look at the process of cellular respiration. Cellular respiration is the process by which cells convert glucose (a type of sugar) and oxygen into carbon dioxide, water, and energy. Therefore, oxygen is needed by the cell and should be pointed towards the cell, while glucose is consumed by the cell and should be pointed away from the cell.
In the given diagram, the arrow for glucose is incorrectly pointing towards the cell, suggesting that the cell is gaining glucose. However, in cellular respiration, glucose is broken down to release energy for the cell, meaning that the arrow for glucose should point away from the cell.
To arrive at this answer, it's essential to understand the process of cellular respiration and the roles of oxygen and glucose in the process. By analyzing the information given in the diagram and comparing it to the correct understanding of cellular respiration, we can identify the error.
