2. In gluconeogenesis, it takes two enzymes to convert pyruvate to phosphoenolpyruvate. a. Explain what is happening chemically
Marina CMI [18]

Answer:1. Pyruvate carboxylase

2. Phosphoenol pyruvate carboxy kinase

Explanation:

The conversion of pyruvate to phosphoenol pyruvate is catalyzed by two enzymes Pyruvate carboxylase and phosphoenol pyruvate carboxy kinase

1. Pyruvate carboxylase reaction

Pyruvate in the cytoplasm enters the mitochondria. Then, carboxylase of pyruvate to oxaloacetate is catalysed by a mitochondrial enzyme, pyruvate carboxylase. It needs the co-enzymes biotin and ATP.

The oxaloacetate formed has to be transported from the mitochondrial to the cytosol because further reaction of gluconeogenesis are taking place in cytosol.

2. Phoaphoenol pyruvate carboxy kinase (PEPCK)

In the cytoplasm, PEPCK enzyme then converts oxaloacetate to phoaphoenol pyruvate by removing a molecule of CO2. GTP or ITP donates the phosphate group.

The net effect of these two reactions is the conversion of pyruvate to phoaphoenol pyruvate. This circumverts the irreversible step in glycolysis catalyzed by pyruvate kinase (step 9 if glycolysis)

How is energy released from a molecule of ATP?
zhannawk [14.2K]

Answer:

When ATP is broken down to ADP

Explanation:

Energy is released from a molecule of ATP when the substance is broken down to ADP

ATP is the energy currency of a cell. It is called Adenosine Triphosphate

When a phosphate is removed, it become ADP - Adenosine Disphosphate.

In like manner, the breaking down releases inherent chemical energy and converts it to other forms of energy.

This is how the body system derives sufficient amount of energy for every of its activities.

When an organism undergoes cellular respiration, this is the process that is in play to release energy needed for the body to function
