Step 1
Give one example of a type of protein within a yeast cell that may change in concentration and explain why this change is necessary.
Answer
One example of a type of protein that may change in concentration is an enzyme. For instance, if there is an increase in substrate concentration, more enzyme may be produced to facilitate the reaction, ensuring efficient metabolic processes. This change is necessary because it helps optimize the cell's function under varying environmental conditions and maintains homeostasis.
