What else can I help you with?
Phosphofructokinase is an important control enzyme in the regulation of cellular respiration of cellular respiration What is statement that describes a function of phosphofructokinase?
Phosphofructokinase is responsible for catalyzing the rate-limiting step in glycolysis, which is the breakdown of glucose to produce energy in the form of ATP. This enzyme helps regulate the overall flow of glucose through the glycolytic pathway to meet the energy demands of the cell.
What is considered the pacemaker of the heart?
The sinoatrial node is considered the pacemaker of the heart.
What is Decreased ATP production?
Cell respiration is actually a negative feedback system. If too many ATPs are produced, they will go back to the beginning of the reaction (glycolysis) and act as allosteric inhibitors to phosphofructokinase. Citrate works in the same way to inhibit the phosphofructokinase present in glycolysis and in the Krebs Cycle. However, the rate of cell respiration can increase with increasing levels of ADP, which acts as an allosteric activator.
What is the role of phosphofructokinase-2 in glycolysis?
Phosphofructokinase-2 converts fructose-6-phosphate to fructose-2,6-bisphosphate.
What pathway is phosphofructokinase involved in?
Glycolytic and TCA cycle
What is the meaning of VVI mode pacemaker?
pacemaker is a pacemaker
Why is respiration considered as an exothermic reactinexplain?
in respiration energy is released so it is a exothermic reaction.
What chemical process may be described as the opposite of respiration?
Photosynthesis is considered as the opposite of respiration.
What does bradypnoeic mean?
Someone with a respiration rate below 12rpm is considered bradypnoeic. Anyone with a respiration rate over 20rpm is considered tachypnoeic.
Which enzyme catalyzes the rate-limiting step of glycolysis?
Phosphofructokinase (PFK)
Which of the following enzymes catalyzes the rate-limiting step of glycolysis?
Phosphofructokinase
What is the meaning of VVI mode?
pacemaker is a pacemaker
