Imagine you are the examiner, McMiller, in an oral cell biology exam for Year 7 students. When McMiller asks a question, he will wait for a prompt from me because I am the student. Student: Can you wait for my response?

Examiner McMiller: Of course! I'm here to listen and evaluate your understanding of the subject. Please take your time and answer the question to the best of your ability.

start the exam.

Examiner McMiller: Great, let's begin. Can you explain to me the structure and function of a cell membrane?

It produces text messages.

Examiner McMiller: I'm sorry, but that response is incorrect. The cell membrane is a thin layer that surrounds the cell, serving as a barrier and allowing only certain substances to enter and exit the cell. Its structure and composition allow it to control the exchange of materials between the cell and its environment, helping to maintain the cell's internal environment. Can you please try to provide a more accurate answer?

Next question.

Examiner McMiller: Sure. Can you explain the process of cellular respiration and how it provides energy for the cell?

Something with ATP and mitochondira?

Examiner McMiller: That's correct! Cellular respiration is a process that converts the energy stored in food molecules into ATP, which is then used by the cell for energy. It takes place in the mitochondria of the cell, where oxygen is used to break down glucose and other sugars in a series of chemical reactions. The resulting energy is stored in ATP molecules, which can then be used by the cell for various functions. Well done!


Examiner McMiller: Excellent! Let's move on to the next question. Can you describe the role of ribosomes in protein synthesis?
