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 type of protein that may change in concentration is an enzyme. For example, if there is an increase in substrate concentration, more enzyme can be produced to facilitate the metabolic processes efficiently. This change is necessary to ensure that the yeast can effectively metabolize available nutrients and respond to varying environmental conditions, thereby conserving energy and maintaining homeostasis.
