Use the information from your lessons as well as the passage below to answer the following true/false questions about cellular respiration.

Understanding Cellular Respiration and Oxygen Release

Cellular respiration is a vital process that takes place in the cells of organisms. It involves the breakdown of food molecules to produce energy. This process not only provides energy but also releases carbon dioxide as a byproduct. During cellular respiration, oxygen is consumed, and energy stored in food is transformed into a usable form for the cell, known as ATP (adenosine triphosphate).

True False
The main purpose of cellular respiration is to produce glucose.

During the process of cellular respiration, oxygen is consumes and carbon dioxide is released.

The process of cellular respiration is somewhat like a mirror opposite of the process of photosynthesis in regards to their reactants and products.

Glucose is the primary molecule broken down during the process of cellular respiration.

Cellular respiration takes place in the chloroplast of the cell.

Only plants perform the process of cellular respiration.

1 answer

Here are the answers to the true/false questions regarding cellular respiration:

  1. The main purpose of cellular respiration is to produce glucose.
    False - The main purpose of cellular respiration is to produce ATP (energy), not glucose.

  2. During the process of cellular respiration, oxygen is consumed and carbon dioxide is released.
    True - Oxygen is consumed, and carbon dioxide is released as a byproduct of cellular respiration.

  3. The process of cellular respiration is somewhat like a mirror opposite of the process of photosynthesis in regards to their reactants and products.
    True - Cellular respiration and photosynthesis have opposite reactants and products; photosynthesis uses carbon dioxide and releases oxygen, while cellular respiration uses oxygen and releases carbon dioxide.

  4. Glucose is the primary molecule broken down during the process of cellular respiration.
    True - Glucose is indeed the primary molecule that is broken down during cellular respiration to produce energy.

  5. Cellular respiration takes place in the chloroplast of the cell.
    False - Cellular respiration occurs in the mitochondria, not the chloroplasts. Chloroplasts are involved in photosynthesis.

  6. Only plants perform the process of cellular respiration.
    False - Cellular respiration occurs in both plants and animals.

For Question 2, please provide the diagram with the terms you need to fill in so I can assist you with labeling.

For Question 3, here are the answers based on the roles of the chloroplast and mitochondria:

  1. My main goal is to produce a lot of chemical energy (ATP).
    Mitochondria

  2. I contain pigments to help capture light energy.
    Chloroplast

  3. Oxygen gas production will happen within me.
    Chloroplast (specifically during photosynthesis)

  4. I can be found in plant cells.
    Both (Chloroplasts and mitochondria are found in plant cells)

  5. I can be found in animal cells.
    Mitochondria (Animal cells do not have chloroplasts)

  6. Carbon dioxide gas production will happen within me.
    Mitochondria (carbon dioxide is produced during cellular respiration)

  7. Muscle cells would contain a lot of me.
    Mitochondria (Muscle cells have a high demand for ATP)

  8. Water production will happen within me.
    Mitochondria (water is produced during cellular respiration)

  9. Glucose production will happen within me.
    Chloroplast (glucose is produced during photosynthesis)

  10. I contain chlorophyll.
    Chloroplast
