Question

Quizplus · Accepted Answer

Phosphofructokinase (PFK) is an enzyme that plays a crucial role in glycolysis, the metabolic pathway that breaks down glucose to produce energy. It is a tetrameric enzyme, meaning it is composed of four subunits. These subunits can be of different types, allowing for the enzyme to exist in various isoforms, which can vary between tissues such as muscle and liver, reflecting the enzyme's adaptability to different metabolic demands.
