1. pump blood into the pulmonary trunk from the right ventricle and into the aorta from the left ventricle
2. it occur as the heart beats, pumping blood through a system of blood vessels that carry blood to every part of the body.
3. incorrect question
Answer:
The organic evolution are basically different from all the other form of the evolution as, the concept of organic evolution explain the origin of the life. It is the events which basically involve in evolutionary development of many species.
It also specifically involve in the modification of various existing species in the nature not only focus on the new development.
According to the theory of the organic evolution, the world are not created it is evolved with the branch of the life science.
Conversion of pyruvate to phosphoenolpyruvate (PEP) is bypassed in gluconeogenesis by using two enzymes.
<h3>How does the conversion of pyruvate to phosphoenolpyruvate take place?</h3>
Pyruvate carboxylase and phosphoenolpyruvate carboxykinase (PEPCK) are two different enzymes that work together to catalyze a two-step process that bypasses the glycolytic stage mediated by pyruvate kinase.
The common metabolite of these enzymes is oxaloacetate.
The steps to convert pyruvate to phosphoenolpyruvate are as follows:
- In the mitochondrion, pyruvate is converted to oxaloacetate by pyruvate carboxylase.
- In the cytosol, malate or aspartate is formed from oxaloacetate and is then converted back to oxaloacetate.
- Oxaloacetate is changed into phosphoenolpyruvate by the enzyme phosphoenolpyruvate carboxykinase.
- Phosphoenolpyruvate reverses the processes of glycolysis to produce fructose 1,6-bisphosphate.
